I suspect I might have ADHD, but am quite concerned that I could even have something worse. I don't know what, but I just am concerned about my manner of thinking and the odd experiences I have at times.
1st time: I am at a party for a young nephew of mine. (I was 15, my nephews were 13 and 10). While I am there, I felt strongly "sped up" and restless and truly felt as though I was on a low dose of some sort of drugs even though I wasn't. This happens to me from time to time other than, to some degree at least. There, I say some things I shouldn't have in conversation with my older nephew in front of some much younger kids.
2nd time: I was at work with a mentally retarded guy who is also gay. We had a full conversation and I gave him my phone number, fully comprehending what I was doing but did not think twice. I told my Dad of this thinking I did nothing wrong or unusual.

I am straight and do not sleep with men, so obviously him being gay had nothing to do with me giving him my number
3rd time: I was at a party with a bunch of total scumbags (people who just got out of state prison and stuff) and although I knew exactly what these people were like I thought little of it once and was still going to hang out with a friend of mine who was tight with some of the worst of the worst there.
4th time: I was at a bar and started hanging out with a guy who was clearly nuts. I could tell, but it didn't register to me to stay away from him. He told me he fought a tiger and I truly believed him even though I pictured him fighting the tiger in my mind. I just thought nothing of it and had no reaction to it

5th time: I went through a brief period of time when I watched porn incessantly and was incredibly impulsive at times and had some ideas about myself I wouldn't typically consider. I ended up planning to get a hooker and even went to a porno theater in the ghetto, but never actually got a hooker just got hit on by some 4 foot tall Indian gay guy.
I have the classic inattention/hyperactivity stuff, but does all this sound like ADHD/ADD or something else because it all has me a little concerned about myself honestly
