What can I do?

Recently I’ve been in a very very bad place. I have had about 12 or so mental breakdowns in the course of a couple of weeks. Im not really sure what to do. I’ve contacted a psychiatrist several times this week but I haven’t gotten an answer and it’s only been getting worse. I’m scared because I’m remembering years ago what had happened to me when I had gotten this bad. I don’t want to relive that. What can I do?
