Hello annoyedgrunt84: I'm sorry you're having such difficulty. From what you wrote, it sounds sort-of like you're in a bit of a pothole right now & having a difficult time working up the enthusiasm to get yourself out. It's been allot of years since I was in grad school. But it still sends shudders up my spine. I often have dreams where I've stopped going to classes & so I'm going to quit school. So it's still on my mind all these years later!
Is there still a possibility of completing your thesis? Could you contact the school & see what, if any, options are available to you? Getting back into therapy sounds like a good idea. A therapist may be able to help you develop a plan to "ungiveup", & provide you with some support in your effort to get going again. It's so difficult to accomplish this when the people around you don't support your efforts. My best wishes to you.
