I am actually insane, a while ago I saw my bfs ex had the same dress as me, (fb stalking) It wasn't my favourite but wore it to my best friends wedding, but once I knew she had it, I threw it out, and deleted any photos of me wearing it, including ones of me and my best friend on her wedding day :(
A few weeks ago, I was Facebook stalking (I know) and a girl that my bf asked out once (didn't have a relationship even) profile picture was wearing one of my favourite dresses, I ripped the dress up and literally un picked it all to a ball of cotton. I'm like a fucking toddler sometimes. 
I purposely wear things I don't like or say I hate things that I kind of like because I don't want to have anything similar to these girls I see as threats. How do I fix this???? I've tried to stop stalking but now I have to check in case they have the same 'taste' it's driving me crazy and it's made me agoraphobic for fear of seeing them in real life. I'm not exaggerating. 
I know this might sound pathetic and silly but I need help
