The pressure makes me want to turn myself inside out

I can't handle the pressure I get in my body and chest everytime a memory of a moment or other people comes up. I know it's easy to day that everyone hates me, but I know for a fact that people in my life don't like me. Otherwise they wouldn't alienate, justify unjust behavior towards me, make fun of and try to humiliate me. I wish I didn't care but I can't handle this pressure
