I think I make it through somehow mostly by distracting myself in any way that I find works, i.e., finding things to watch that keep me interested and aren't depressing, if I can make myself listen to music which for some reason I find difficult to do when depressed, it is always amazing how much it helps, reading, crying and sleeping. Coming on PsychCentral everyday helped me tremendously also. Otherwise, I really don't know how I make it. Oh, getting back to therapy & a med change helped of course.
I hope you're feeling better soon.
