I know EXACTLY how you feel with the stress of projects. I just finished my semester and I have to say I feel for ya. I had papers to write, a resume to make, all for one class, while I had to print out 20 photographs (the old fashioned way) for my art class. Also I had to do exams, I had waited so long it all came down on me like a falling brick wall. But it eventually passed, and I passed my classes (barely).
I hate to say this, but, from my experience, your depression........... is from the stress of those projects!! !! Was with me at least. It's EVIL. You can't work due to depression, and are depressed cause ya can't work. I would suggest doing a fun project on the side (writing a story) to get you mind pumped, occupied with some enjoyment, and ready to work. Or, do something fun while you make a mental outline of the work, get done with the fun, and race to get done with it. They always get easier as ya do em. Otherwise, find a friend online, start a chat session, and have them toss ideas at ya on what to do. Just my two cents to add.
