This sounds pretty similar to me. I'm 28, live with my parents, and quit my well paying IT job about 6 months ago. I felt better for maybe a couple months after that, but started getting pretty depressed again. I've been out of work this whole time and its making it hard to find any employment now which may not be the worst thing as I am still not in a very good place emotionally. I've lost any semblance of motivation that I used to have. I recently started retaking my Wellbutrin but feel more lost now than I have ever been. I really don't care about IT and have yet to truly find anything that I enjoy doing. The thought of having to work unsatisfying job after unsatisfying for the next 30 or so years scares the hell out of me, but I don't really have any idea of the type of work I might like to do or what I might be good at. I don't have any significant marketable skills and it feels like I'm just floating aimlessly waiting for something to happen or change for me. I know nothing will get better unless I help myself, but it all just feels so pointless. I really really hope that we can both find some purpose and peace in life sooner rather than later.
