I'll keep it brief and to the point.

Backstory:

My mother died before i went to college. Spent the first few months in severe grief, but managed it by partying and doing reckless stuff. Met a girl who seemed to genuinely care and caught severe oneitis. Took her on a date got rejected. Did some stupid stuff trying to get her back, pushed her even further away. I want to forget about her, but every time she's mentioned or I see her I get an anxious response. I want to forget about her, but don't know how to. Feeling still there even after a period of no contact.
