I'm not questioning your diagnosis but what you just described sounds like any kid who falls in love for the first time and gets super overly jealous and paranoid of the girlfriend. Especially the jealousy about previous sex partners. I read about it all of the time on reddit. You were even a stoner which must have contributed to the paranoid thoughts.

I hope you're not smoking weed anymore because in your case it might be a catalyst.

Did you become more morbid/ Are you more focused on death? Do you feel a change in your maturity? And does your hair grow over the scar?

All the best man!
