Peoms about cheering

I (19F) have two ex's B (23m) and K (23m),
I met B through my step-brother J (31m) when I joined my brother in a GTAV crew on the Xbox back in early 2021, I grew to like B as more as a friend along with another crew mate; T (32m), I was 18 at the time I met B and T.
Things went haywire in that crew causing my brother to leave it, taking me with him because our mum (49F) asked him to look after me while on GTA, I was in a group chat with B, T and one of the crew leaders TR, I did join B in his personal crew.
This how the chat went;
Me "I'm also in another crew, both me and my brother joined them, we're under their protection"
B "U didn't tell me about this, which crew?"
Me "this crew, (says crew name)"
When I said their rival crew's name things became hetic, the two crews used to be combined into one big crew but something happened that caused a rift between the two.
B "What?! Hang on! Why u in there?!"
Me "My brother joined them and I have to follow, sorry and I know about the history you have with them, it's just drama going on"
B "No offense but that pissed me off"
T "They screwed (crew name) over! Why run to them M?!"
B kept on trying to get me to leave that crew, saying I will get kicked because I had his crew tag as my active one, along with saying he needed to be there so he and T could protect me?! Then things got out of hand to the point I actually started to cry and my brother came to comfort me.
B "So you will have to make the decision, on what you are going to choose"
T "Them or us?!"
B "Remember who has always been there for you"
T "We have!"
Me "You're making me choose?"
They confirmed it, bringing up the two crews past, along with saying me and my brother will get screwed over, I put one last message in the chat before I left.
Me "I'm sorry but I have to be in my brothers crew because he's my family, he can look after me and if you're making me choose, I choose my brother and (crew name), I thought I could actually trust you, but I thought wrong and to think I actually liked you as well T, I lost a friend and a brother because you two can't let go of the past... Maybe in the future you'll realize that"
Me and B had one last conversation before I blocked him on messenger
Me "When you get over the past, let me know"
B "What do you mean, the past? I feel betrayed coz I trusted you and I've always been here for you and you go and do this"
Me "When you let go of the past, I'll see if our friendship is worth it"
This wasn't my finest hour but I was hurt that they didn't leave the past where it should be.
When things had settled down, me and my brother got kicked out the crew because the crew leader didn't allow us to explain what happened but not for the reasons B and T kept on telling me about.
I regained contact with them a couple of months later, they added me back to the chat and I managed to find out that they kept on calling me a "back stabbing b*tch" along other things, I didn't think anything of it and a month later got with B.
I met K through B, me and B also helped T get with F (23F, B's ex as well), everything was going well in my relationship with B, well... I thought so anyway.
Back in November, a couple of days after my birthday and getting my tattoo, I broke up with B because he was lying and threatening my family along with not stop drinking every weekend, I joined a crew that I met through B and K, I was just in that crew for a month before things became complicated.
K started being really flirty with me, I didn't think anything of it, I thought he was just trying to cheer me up because I wasn't over what happened with B, things got intense fast, it turned from joke flirting to real flirting fast, we talked a lot on Snapchat and messenger.
My family knew something was up and did their own little investigation about him (my parents are semi-retired predator hunters) what they found I didn't even know about because he never told me, he had a girlfriend!
As soon as I found out, I tried breaking things off with him but he said that my family found his old Facebook and they were broken up for a couple of months at that point.
I took him for his word (my mistake) and continued on with my relationship with him, only to find out a couple of weeks down the line that he and his GF were just on a break and were back together, the rest of the crew found out because he lied to them about the reason he had me blocked on everything.
I broke down crying and told them (including the crew leader) everything that happened, my parents came into my room and weren't happy to see me in tears. My parents said that K used my Autism to mentally mess with my head and because I was still heart broken over my previous relationship.
K tried saying that he didn't know I had disabilities, that backfired on him because the crew leader S (40sM) told him that everyone in the crew knows about my disabilities because I'm open about having them.
K then left the party because every bullshit excuse he tried coming up with, everyone saw through it. I left the crew because of my mental health.
A couple of months pass and the same thing happens again, this time K told me that he broken up with her, I was with someone and K fucked with my head and again I was under his spell, I broke up with my then partner and got with K, another mistake.
I met my current partner L a couple of weeks after I got together with K, things were going well till K slipped up and gave L a "loyalty test" K told L that he was going to a hotel with his girlfriend, L came and told me, I confronted K about lying but he said that he wasn't with her and just wanted to test L's loyalty to the crew, it wasn't a test to the crew, it was to him.
The next day K tries using me to get to L, to attack him on GTA, it was then I looked back on my relationship with him and realized he wasn't who he said he was.
Pullying me out of crew parties and into private ones whenever he had a temper tantrum, ranting about how the others never played fair, slagging other crew members off behind their backs, verbally abused me when I joined his party just to say hi to someone else, used me as a verbal punching bag, lying about him and his GF breaking up and threatening to send my nudes out.
I don't claim to be a saint because I did my fair share of shit, a couple of months later I do admit to use K to apologize to him and the main part of the crew about the things I caused for them, a means to an end sort of thing.
I said to them that if they want me in their lives, they'll have to be the ones to reach out then left the party and blocked them all on everything, apart from 1, BL(40sF) on Snapchat.
BL messaged me asking about K, that's how I got in to talking again to the crew but I'm in BL's crew which is in an alliance with S's crew, K didn't like that I was back in contact with S, BL and D (32M), he joined the party and started to verbally abuse D.
Both the crews share the same crew tag and S has told K that because of him harassing me, he's not allowed back into the crew and I was back in contact with T who asked B why he harassed me among other questions. (I've got almost 2 months worth of screenshots of harassment from him and his mates)
Turns out that when F and T got back to T's house, F and B were having an affair when me and B were at the 2 month mark of our relationship. B didn't even regret cheating on me, he didn't even care, I have reported B to the police for harassment and he and his friends has backed off harassing me because he got a visit from the police.
But K is still causing trouble, he took a picture of my Xbox account and post it on his Snapchat story, telling people with Xbox accounts to create multiple and I quote "harass the bitch" I only know about this is because of a mutual friend I made through K, he took a picture of K's story and sent it to me.
I don't know what to do, I've already gone to the police about B because I've got almost two months worth of screenshots but with K I've barely got a weeks worth and my mental health has suffered enough because of B.
I managed to take back my life from him because I uploaded a Spoken Word/peom I wrote on YouTube called "Time Isn't Love" because I wanted to get everything B has done off my chest, I used my independence project to do that but now the nightmares are back, I barely eat, drink of sleep because of B and K.
Any advice on how to handle this, BL said for me to let it wash off of me while D said that I need to get angry and let it out or break down and just cry but I can't do any of that because I don't want my past to be part of my present anymore.
Edit to add:
Because of everything going on, I'm underweight again for the third time in my life, B and a couple of his mates actually took the mick out of it and started calling me fat, I went bowling with my college as end of year treat, I managed to eat 2 slices of pizza instead of my regular two, I looked down and saw that I put a little bit of weight back on and became excited! I had a friend take a picture of me from my side and had my stomach out so I could post it on Snapchat, I was glad that I was finally getting my weight back.
