Go to the doctor. I don't know you beyond what I've read on your journal in the last couple of months, but I know you're a good person and fine writer who's been under a lot of stress. When life's hard and you have options, don't hesitate to take them, if not for yourself, for the sake of the people you love.

Okay, that's my gratuitous nagging of the day. Here's hoping things look better sometime soon!
