Please try to see your psychiatrist sooner. I think that's much too long to wait to be seen, if you can possibly do something differently.

When I am very deep in the hole, I try to plan just for an hour at a time to get through the day. Having a responsibility of some kind is absolutely imperative. My recent round of hell, which was largely due to my medication regimen no longer working well, was hugely exacerbated by having too much time on my hands. It was semester break, so I had no school or work commitments, and that was a recipe for disaster.

I do better when I create commitments in my life.
