Hey,
Have you been to a Psych doctor, yet? If not, I would try to find a therapist, first and get an idea of what all you are dealing with. I had similar symptoms that you did. The not being able to fall asleep had to do with my anxiety and worry that I was going to die and that everything was falling apart. I was depressed all the type to one degree or another. Unfortunately, I was given an SSRI (Zoloft and then Celexa) and I wigged out on it. I became not only manic; but, psychotic! I went back to my doctor and he asked about Bipolar in my family and I really didn't know. I did know that I never felt like that before, just when I tried LSD once. I ended up with another Psych doctor and he told me that because I had a medication induced manic episode, I was bipolar. This pi**ed me off because talk about a career destroyer! He stuck me on these awful medications that did nothing for my depression and pretty much made me a zombie.
What I am telling you is that you need to go to a Mental Health specialist if you haven't already; but, read up on the medications they prescribe you before you start taking them. If you find out something that doesn't sound right, ask you doctor again about it. Not all these guys really know what will work for you and what not. Everyone reacts differently and it sometimes takes a while to find the right medication.
I am now on Klonepin because of the anxiety and I have PTSD (contributed to my inability to sleep well) and I take Wellbutrin because I suffer from chronic depression. So far, it has worked good for me (although the Klonepin can be addicting so you have to watch it). I got these prescribed to me by a totally different doctor. I actually went off of all those Bipolar meds on my own because I felt like s--t on them. I told myself that I would never go to a psych doctor again. I ended up in a major depressive episode about a year later. So, I went to another psych doc.
Try to get to a good doc. If you need a reputable website on medications and disorders, try the National Institutes of Health one. (PM member for website).
