First world problem

This is going to be a very first world problem kind of post, but I tend to write heavy shit so. Anyways, as I've said, my dad was horrible when we were kids. Physically abusive and I hated coming home from school. I genuinely hated him all my life. Well, now we're adults and he's completely changed. He seems to want a relationship with my brothers and I. My brothers latched on immediately. They wanted to be his friend. They constantly play games together, like rn are playing terraria. Which I'm bummed I'm not a part of but we're playing borderlands with me involved, just they started a new game to give me space for my surgery. Anyways, my dad made bbq and I know he misses my brothers because they would eat so much. And I just can't. I'm on tirzepatide. Even though I'm coming off for a bit for surgery, my body is still recovering. And my dad has kept making comments about it like guess you don't like it and shit. When my stomach is in actual hell anytime I eat this much protein. I've been in so much pain today. He called tirzepatide evil but doesn't seem to understand. And I know he wishes I was one of mu brothers. My mom plucked me out of the group and still keeps doing it. She keeps telling them to play without me for no reason. It just makes me feel isolated. And kinda jealous. Terraria is something I really wanted to play with them so I’m bummed about that
