finding out you have something bad.

I need some love and comfort. The first time I had sex was over a year ago & after that happened the guy left and never spoke to me again (and he apparently had 3 other girlfriends) but about a week ago I got tested for stds and today I had to go back and I have clametiea and I was given pills and stuff but I'm just really upset and disgusted with myself bc I'm only 15 and this is humiliating and sense I did have sex and he left the way he did I made a vow to never do anything ever again which now I definitely never wanna be touched EVER again so idk what I'm supposed to do and I'm kinda just scared.
