Does anyone have advice on how to deal with irritation?

Before getting sick I was always really nice. I still feel nice, but I never thought badly about people. But now I’m struggling horribly with irritation from even the smallest of things.

I hear my roommate breathing and I get so angry that it makes me want to start sobbing. She talks and I want to scream. Everything is so loud and overwhelming. I just don’t know what to do because I can’t be like this. I don’t live with accepting people and I already have to mask so many symptoms, I just need to figure out how to hide this one too so people don’t give me a hard time. I can’t handle people giving me a hard time anymore. It’s too much and makes all my symptoms feel worse and I don’t ever feel rested enough to be mentally well. My doctor said that he believes my MECFS is causing emotional dysfunction/dysregulation because of how unrested I always am/feel.

Sorry for rambling, I’m just feeling terrible. I’m always overstimulated, overwhelmed, exhausted and sick. I just need to find out how I can hide this or something so everyone won’t get mad at me. Last time I had a meltdown because of my pain and emotions my roommates made me move out for a few months. I can’t do that again.
