I'm so sorry you feel this way. I can really empathise, because I have been there so many times, and I also, occasionally, feel like my therapists, especially the one I have been given through university, feel like they are pulling teeth with me. But honestly, they are just doing their job, and it's a job that most of them love doing, otherwise they wouldn't be doing it.
I agree with the others; go out and find something you enjoy doing. Volunteer, take a class, whatever strikes your fancy.

Unless, of course, like Gavinandnikki points out, your depression is so bad you don't feel like getting out of bed - if that is the case, get yourself to a doctor instead!
