I've been struggling with increasingly difficult anxiety, depression and weird sensory overloads (I didn't know what they were until recently) for 10 or more years and I was more or less miserable all my life. Anxiety and depressions come in periods. At one point the psychiatrist though I had Bipolar, but I don't have any manic episodes really. I may go from depression to anxiety in one day, but it's never really manic episode. So he shelved that. It seems to me that prolonged anxiety causes mental burnout and fatigue that give grounds to depressions episodes.
I also have some symptoms of PTSD, social anxiety, general anxiety, obsessive personality and probably few more things. The doctor was lost but he never even hinted Asperger's. Then I started Cognitive Behavioral Therapy. It's done by a psychologist and he said right away that I have AS and I should find someone who specializes in Autism spectrum and get tested. I started reading about it, including some Medline papers (since I have easy access to a university library) and Tony Attwood's. I also spoke informally to a couple of other psychologists and psychiatrists who do research at the institution I work for. It all clicked in place. On any self-test AS I come in the 70% range. So I found a place, a center for Autism and I went through a long pre-test evaluation and the psychologists said it definitely does look like AS. The actual testing is still a few weeks away, in December. So yeah, it looks like I may have AS or HFA (although they're supposed to be pretty much the same, right?) and on top of that load of other issues. It seems, according to Tony Attwood's book, that many people with AS suffer from other disorders that are secondary to AS. It also seems that many psychiatrists fail to notice that connection and only treat you for the secondary disorders. I consulted other psychiatrists and none mentioned Asperger's. They just wanted me to try more pills for depression.
