Kent, I agree with Kaliope. I guess it all depends... does your girlfriend know about your depression? If so, is she supportive at all? I definitely think that if she's willing to be there for you, she's patient, and a GOOD supporter of you, then you shouldn't break up with her. But if she's not very understanding and impatient, then it might be a good idea to break up with her, because such negative influences would only hold you back.
