Hopefully you won't have to wait too long for the next appointment. Be sure to write down any questions you might have for the new doctor. I find that the time goes by so quickly sometimes that if I don't write things down, I forget something that I wanted to talk about.
Most importantly, don't stress about it too much. Just focus on trying to find some balance and keeping yourself as grounded as you can. Do you have a therapist or are you just seeing the psychiatrists for now? It may take some time, but things will be sorted out.
