Coping with aniexTy and depression

I'm just a little over 20 weeks pregnant, and lately I've just been so stressed out and I can defiantly feel the depression I used to feel years ago again, I don't wanna eat. I either sleep none at all or sleep too much. It's a struggle for me to get out of my house every morning to even go to work. Being around the people just makes me have a panic attack every time i get there. Since I haven't been eating I can feel my body beginning to shut down on me. I'm constantly weak. My doctor won't see me no earlier than my normal appointment in 2 weeks. Since I know there's other woman going through the same thing, how did you manage to cope with it all
