A similar thing is happening to me too, a lot of things have happened in my life recently that are causing stress and have thrown me into a severe depression. I have tried to get back on my antidepressants as I have been off, but my doctor's office keeps sending me to a voicemail where I leave a message and nobody calls me back. Awesome.

I don't know if I have much advice for you, as I'm not quite sure what to do myself. Headaches every day, sleeping 12 hours a day, crying every day, wanting to do things but then not doing them. Anti depressants might be a good thing to look in to. I sympathize, and hope you start to feel better soon!
