You should probably find a therapist to help you. Clearly whatever you’re doing isn’t working. A therapist can guide you through the process of letting go.

Dude relax, shit happens in life, it's hard to forget a 2 year relationship but before loving her, you gotta love yourself, then it will be damn easy to move on, start loving yourself do some things you really love example:- learning guitar, play some sport.
You have a long life to live.
She's not the only girl out there, you will find a better person who really really loves you.
