This site isn't for real confessions, its for making up sex fantasy confessions. Sorry, you need to find another confession site
I know how you feel. It's really hard to balance the need to help your family and the need to protect yourself. My family went through a rather nasty divorce, with my dad being a total douche, and now I suffer from anxiety issues and I lose a lot of weight very easily (I'm perpetually underweight now) because I tried so hard to help them instead of myself. I can't stand to feel selfish so I don't take care of myself emotionally. Hang in there. I know it's tough, and it'll probably keep going for what feels like forever. Bad things always come back to equilibrium, and hopefully your family will be stronger for it. I wish you the best of luck!
