Kind of new to reddit and I’m not sure if this would be the place to ask for tips. 
I’ve been struggling with these my entire life but since the beginning of 2019 they both have gotten extremely worse. I grew up in a broken home and recently had to cut my family out of my life because of how toxic they are. They slashed my tires and keyed my car just because of assumptions when I didn’t do anything wrong. That has killed my confidence and made my illnesses worse because I lost my family. I’m also currently married and my mental illness is affecting my marriage because I overthink and jump to conclusions and I look at things when they have no meaning, and give them some twisted, dark, and horrible meaning (if that even makes sense). I swear that one day my wife will cheat and that I’m not enough when that is not the case. I have crippling trust issues and my mental illnesses make it worse because I think that others aren’t capable of staying loyal or being loving forever. One day I can be bouncing off the walls and doing my best to make my wife smile and just boost everyone’s mood and the next I want to overdose and slit my wrists because maybe it’d just be easier to give up on life instead of continuing to strengthen my marriage and mental health. Has anyone found any things that at least put a dent in coping with these illnesses? I love exercising and I’m into body building and powerlifting, but my anxiety and bipolar depression have gotten to the point wear lifting weights isn’t cutting it anymore.
