Unhealthy vices I use to cope with my problems and what healthy alternatives I could try instead

I have sex with random people as a form of self harm because it leaves no scars for anyone to see, no mess to clean up and no explanations to give. There are no healthy alternatives at this point, I used to self harm with over medicating again, unnoticeable unlike cuts or burns but now I’m on so many meds anyway it has lost its appeal. I get checked out every 12 weeks to make sure I haven’t caught anything so it’s not about risking my sexual health, I just hope one day I’ll find a lunatic that will turn out to be a killer who will murder me. Until then I can use the fake closeness to emulate something close to someone wanting me for real.
