I really understand wanting to isolate. But the problem with that is that we're stuck with only our own voices--or old tapes of others--in our heads. Not a good idea when we're 'way down.

Sleep can be a great healer, but if it didn't make you feel calmer, then add help to that.

Today, on a thread, I read that we don't have to support others all the time, and that sometimes it's ok just to ask for support. Maybe you need solitude in order to think and begin anew. But if you are using solitude as an escape (description sure sounds like it), then it's not really working...I'm glad you're posting here. And maybe post in the depression forum also?

Another thought: I don't think it helps to tell ourselves global goods--like, life will improve. It feels good to me, though, to say that I can improve my thinking, as in there is no "only" answer. There are many answers. Can you talk to your boyfriend about what the specifics of your life are and borrow his brain to help you think of changes you can make? Also, even if you can't see your therapist for a week, can you call him/her?

Many, many hugs. I'm sorry you are so sad.
