I used to be a disaster - self-harm, sex, drugs, alcohol, anorexia, didn't go to school, couldn't hold down a job - I spent over two thirds of my 20s in hospital, I worked it out. I'm 32 and I'm doing so well, I'm working (2 jobs), I'm going to university, I'm in a relationship (sort of), I'm not harming myself.  
  
I'm in a shitty situation with my partner,basically he found out what a slut I used to be and is now treating me accordingly. I'm bouncing between wanting to be my best self and wanting to destroy myself. What he's doing is just confirming my worst fears about being honest. 

I really want to self destruct but I know I'll regret it. What can I do?
