I can’t deal with the topic of mental health

Anymore. My abuser used his mental health as a weapon against me every time he felt like I did something wrong. He would always threaten me by saying he will kill himself if I don’t love him or if I talked about my feelings that were negative. If I typed the wrong emoji he would start crying and saying he’s gonna kill himself because I thought he looked like that emoji in his mind. He was clearly mentally ill but now I can’t stand to be in a room with someone that has a history of mental health issues because it just scares me now I’m scared that I’m gonna get treated that way
