I have (quiet) BPD and the ex I'm still struggling to move on from got diagnosed with Avoidant Personality Disorder.

That explains so much.

Yes, you can laugh at me now.

Did I mention we still live in the same house and she's dating someone new which makes me wanna die everytime I see them together? :D 

Or that I can't move for the foreseeable future?

How did I get here.. *facepalm*
