Didn't find out I had autism until 2 years ago. The damn psychiatrists up here in Alaska are 95% rejects that barely passed their boards. They'd been treating me for the 4 years prior to my diagnoses as a Bipolar with no "Good manias", just the bad ones, the dysphoric manias. My "Ups" were flat-line neutral moods.
To the point, I am glad I finally got the correct diagnoses of ASD, since I'd spent the previous years in treatment for bipolar, the drugs of which nearly drove me insane. BUT, Autism is just a curiosity to me, an explanation for my quirks.
It's my MDD that's going to kill me, not autism.
