This has gone on too long! In my life, I went through 8 months of straight hell, and in 2000/2001, one year of absolute hell. Enduring anxious depression has been the worst experiences of my life. I don't know how I survived. The right med combo pulled me out so that psychotherapy could work. The waiting time though ... I never want to go through that again. I'm scared that I will go back to that place.
We have similar experiences in symptoms, severity, and duration. It pains me that another person is going through it. I wish I could help you.
Your prescriptions are appropriate. (Although, I think you deserve a long acting benzo like Xanax XR or Klonopin for now to bring the anxiety down.) It's just a matter of waiting to see if they'll work for you. The waiting, dear Lord. What are you doing with your time?
What I did was watch mindless TV. I loved Monk, Law & Order, Bones, etc. I put together puzzles to keep my mind occupied. I colored. I went on walks around the block. I did everything I could to hold myself together until something worked. And yet, I still went in-patient. I swear, it was the best thing I did. It was hard putting all my trust in the staff, letting go of all my control. I cried for days.
The most therapeutic value of in-patient care is that I was around others who understood. I had no need to explain my disorder to the other patients, vice versa, and we could talk to each other like normal people. I felt normal, despite all the panic attacks. I felt comforted. I still keep in touch with them. They are lawyers, teachers, artists, etc. I'd have never guessed that they struggled.
What I suggest is to:
1. Keep yourself busy during the waiting time. When people do left-brain activities, like counting prime numbers or doing Sudoku, it pulls their attention away from the right brain, where the emotions live, and can lower anxiety and depression.
2. Sleep all you want.
3. Go to support groups, like AA or NA, just to listen, because by seeing others struggle everyday and survive, you may start to believe that you will get through this too. Dr. Marsh Linehan (famous ground breaking psychologist) suggests it. Please consider Emotions Anonymous if it is available in your area. It is not prevalent as AA and the attendance tends to be lower, but I do think that connections with others who suffer will help. I go to EA as much as possible.
