I totally agree exercise is a big help ,take a long, brisk walk with your dog ( a dog itself is a great help if you live in an apartment that allows pets) or simply push your self to go alone, I know you feel like absolute crap but exercise will help. Personally I started small on the days I could at least get out of bed and then built up, as i said I fully get it - bed was my sanctuary when depression was bad and it still is some days but exercise is hard work especially for us, and laying in bed is easy, push for one month and i bet you feel at least a little better.
