Hello Futurestreet: Mental health diagnosis is a job for professionals. So really, what needs to happen here is for your bf to see a mental health professional who can help him to figure out what is going on with him. However, perhaps some other members, here on PC, will have some suggestions to offer.
I see this is your first post here on PC. So... welcome to PsychCentral… from the Skeezyks!

I hope you find the time you spend here to be of benefit.
PsychCentral is a great place to get information as well as support for mental health issues. There are many knowledgeable & caring members here. The more you post, & reply to other members’ posts, the more a part of the community you will become.

Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
