Sorry, I can't give any good advice about you and your girlfriends relationship...I haven't been in a relationship in well over 5-6 years and the last relationship I was in was very dysfunctional, there rarely was a time that me and my girlfriend bonded...as far as your depression though? I can relate better to that. From my experience, it can take months for therapy to help (plus, finding a good therapist isn't easy either). Taking an online depression test is a good first step, but I'd take it to the next level and see a psychiatrist if you think you are clinically depressed. From my experience, the longer you put off getting some help the longer it's going to take to treat the depression and you don't want to end up severe depression that could last years, that could take a big chunk of your life from you. So I'd make an appointment with a doctor if the depression is consuming you, regardless, of what your therapist says...you can ask him/her too though, just to see what they think...medication is usually the last resort but sometimes it's necessary in severe cases. Take care of yourself.
