Stupid insensitive relatives

I was first diagnosed with depression in my teens. I was supposed to be medicated but No my parents wouldn’t do that. I left home early to get away from abuse and thought I was running towards love. I was wrong. I tried going to hospitals for help but I had no insurance so it was like I didn’t exist. Years went by and I got worse. Eventually I snapped and tried to kill myself. Recently I found out I have a heart condition and had to go to the hospital. They told me not to work. I applied for Social Security but it’s taking forever. My relatives know all this. I was forced to live with my mother and she’s incredibly rude and nasty. I had to fight with her to finally get medication for my mental health. She has no respect for me and talks to me like I’m garbage. She even expects me to give her my entire paycheck when I have been able to work. It’s like when I was a teenager she screams about money, threatens to kill herself and talks to me like I’m Satan. She could care less if I have anything at all for myself. Her asshole friends post anti gay crap on Facebook and she likes it. She publicly humiliates me to make herself feel good. She just started screaming at me again. I know she never loved my biological father, he had money and she wanted it. She only had children to make damn sure he was financially screwed when she finally left him. I’m severely depressed, have PTSD, a heart condition, and I’m shaking from anxiety right now. What the fuck wrong with a person that knows someone is sick and yet they just abuse them nonstop.
