Cupons for boyfriend

F (20) 150lbs 5’3
I am aware that the main issue here is my mental health and my dedication, but it feels like an excuse always comes up to eat. My mental health has been shit for a long time, I think I may have a binge eating disorder but have not been diagnosed. But there’s days where it feels like I can’t stop sometimes I eat something and realize I don’t even like what I’m eating all that much but I’ll eat it and I’ll finish it.
I’ve been trying to limit myself but it feels like every time I do I always have someone telling me not to. My boyfriend is wonderful but he is also overweight and loves food just as much as me. It’s not that he wants me to be overweight but he’s always like “hey do you wanna pick something up today” and if I don’t he keeps being like “but I have a cupon” or this and that and it just ends up with me saying yes. He doesn’t mean any harm if anything it goes to show that we are both addicted to food. Then there’s family events. I come from two Mexican parents that love cooking so you know how that goes. It’s really hard to not over eat when I’m literally being encouraged to get a seconds every time I’m with them. Then there’s my boyfriends family who is the exact same way but just the white version.
Thanksgiving is coming up and I’m fucking terrified. I don’t want to put my body through pain just for some bad food that’s gonna make me feel good. But I genuinely feel like I have no control then after it’s Christmas and then after it’s Los Reyes Magos (three kings day) and I just feel like it’s never ending. It’s either a birthday party or an anniversary or a holiday it just never stops. Any advice on how to have a stronger will to stay healthy?

I went to a random store and followed it. The store gave a code for 42$ off a 50$ purchase. Everything went normally. Had a bill of 9$ for 50$ worth of clothing.
Upon ordering the seller requested i cancel. I'm confused. Did they fuck up their cupon? My boyfriend says i should not cancel under any circumstance.
Will they be able to retaliate if I don't cancel? They haven't told me whats wrong with the code.

Hello all as most of you here I was dumped by the woman who I thought was going to be my forever. I made the announcement to my friends and family and even began looking at engagement/wedding rings. Then one night I get home from a long busy 10hr work day and the first thing she says to me when I say, "hi babe" is.....,"we need to talk. I want to break up." To sum it up short and sweet she said that we have problems and the only way to solve them is by breaking up. I tried to reason and she told me to not make this difficult she made up her mind and she's not going to change it. So a little insight to our relationship for you all to enjoy. I was by no means the poster child for a great boyfriend nor was she the greatest girlfriend. We'd both have moments where we'd say we will do something but end up not doing said thing. For example and one that I 100% wish I could go back in time and kick myself in the ass and make myself do was going to Victoria secret to pick my GF some sexy things. She had received about 8 fantastic cupons from Victoria secret and pink and was super excited for them but they expired pretty quick and she was busy all week so I said I'd go on the weekend for her. Spoiler alert I didn't go instead I played videogames all day and it wasn't until I got hungry and went to get food when I remembered I promised to go and I was too late. They closed and the cupons expired that day. Needless to say my GF was not happy with me. I truly regret not going. Now she on the other hand was ALWAYS going into work even on her days off. It was like if anytime me and her had anytime together her work would "randomly" call her in and she'd go no questions asked. She was excited once because she was finally getting a day off in 2 weeks and it was on a day I had off and me and her were talking about what we were going to do and we went to bed and I woke up at 730 to go to the bathroom and I saw her getting dressed for work and she blankly said to me "oh yeah work called so I'm working all day." That made me so mad everytine I heard her say that but I guess in her head it's okay. I don't want to make this too long and drawn out so if you'd like to know more about things both she and I did I'd love to chat.
