Hi Mike, welcome, good questions. Chill dude, you can't really hope to diagnose yourself with this stuff no matter how comprehensivs a list of symptoms you may come across. The thing is, all of the dx's share symptoms. I'm bipolar for example, but have the combo sampler plate of symptoms. (I am hardly unique in that respect)

One of the most effective things you can do to help a therapist dx you correctly is to keep a journal to chronicle your symptoms, moods, and ideas. Many of us didn't do that, and had to start with dx's that only reflected what was most on our mind the day we sought the Dr.'s advice. See what I mean? Bipolars generally don't look for help when they are manic. They go in all depressed begging for pills. Doctors like happy customers too, and if you make it easy for them, well, they're human.

Sqrl's advice to Mike: stick around, read, post, share and learn, and keep a journal. Glad you're here.

P.S. I have all of the symptoms you mentioned, minus the lump on the head, and I'm not Schizophrenic. Now that I think of it, my head is sort of lumpy. lol.
