I think just tell the bf that you can’t  be with him this weekend, you’re in over your head in homework. Hopefully that actually works, and you can get your homework done over the weekend, and then you can start stressing over your crazy significant other.

In any case, best of luck to you.

Failing that, seek professional help yourself FOR your BF, Maybe they can give you some ideas, or help. I’m not too sure how American GP’s/Doctors work, but thats what I’d so here in Sunny UK.

Ditto on what TSD said.

Do what you need to do.  You have the best intentions at heart.

I agree with TSD and Ninty. Focus on your work this weekend. Then worry about the bf...as bad as that sounds.

If I may do so, I agree with all of the above.

I haven’t had to deal with a person with bipolar and/or anorexia, and I wish I had advice to share with you that might help you cope with his problems.

He doesn’t seem to have the mental capacity to know that he needs professional help, I hope that you can convince him of that.
