Justy -- I'm wondering if you may have ever considered these things:

(a) The only person responsible for your BF's moods and emotions is your BF.

(b) That you may be in an emotionally abusive relationship? Abusers always convince The Other partner that "It's all your fault that I behave this way."

I'm not buying how great your BF is about educating himself @ depression if he uses is to put you down, make you uncomfortable, and has decided he knows more about meds than yr p/doc. Reading a book or two does not give him a medical degree and a license to practice.

Sorry. You probably don't need to think @ these things on top of everything else.
