I'm a 20yo college student with a seemingly normal life. My grades are pretty good, I make a good amount of money each month and almost everyone I interact with seems to trust me (friends, teachers even strangers).
I've had one serious relationship while I was in highschool which lasted for about 4 years. Ever since, I've abstained from sex in order to focus on my academic achievements and financial status. In the past two or three years, I've had maybe 4-5 attempts to build a healthy relationship with a girl. Needless to say, every single one of them was a bit of a mess and resulted in me having 0 sex.
I went through depression and anxiety caused by another issue of mine which was hypochondria at the time only to find myself being reckless and sexually lustful.
The first thing I noticed it was wrong with me was that I had started to take creepshots of girls I found attractive on the street, at school etc. That went away, but masturbating and fantasizing about girls I knew was a legit sport for me. Their social media profiles were the El Dorado for my sexual appetite. Everything was fap material, I could literally jerk it to a picture of a cute girl in a ski suit.
So, I started looking for people just like me, creeps who had nothing better to do with their lives but to stalk beautiful looking women. I did find them and it was all fun and games until, out of my characteristic poor judgement, I exposed some girls I knew on a public forum. The emotional and psychological impact that reckless act had on me was unimaginable. I couldnt even breathe properly thinking that one day, the girls I exposed would find out about what I did and call their boyfriends/families to hang me or to take legal action against me; whatever worked for them.
Fast forward 3 months and the forum in cause is dead because it wasn't exactly filled with the nicest of people (some had rape/snuff fantasies or even worse) but the scars still remain and I'm still fantasizing obsessively over these girls, all of which have boyfriends. I have folders filled with their pictures, some photoshopped in porn scenes, some with them receiving facials form fake dicks.. you get the point. Nothing changed, except never will I ever expose or degrade anyone in public, knowing the harmful effect it had on my mental state.
I even went to a psychiatrist appointment and all he had to tell me was to go see a priest and pray... But I think my situation is far worse than that and there is potential of ruining everything I've built so far: friendships, academic achievements and I might even lose my family's trust in me in the event that the forum comes back up and someone bothers with finding out who posted those pictures in there.
What should I do in order to get rid of these obsessive thoughts and creepy/stalkerish behavior which might in the end lead to more serious stuff?
