Triggers?

I didn't have a lot of friends growing up. I got diagnosed with adhd, and whether or not it was right, I got teased a lot, and got on everyone's nerves- including my parents. I spent a lot of time reading. At the time, I was told what I experienced was "hyper-focusing". I can read for hours at a time, but the longer I do, I start to get The Feeling. It starts with my eyes every time. I have trouble keeping them focused when I look up from my book. It happens on days when I am alone for long periods of time too. Sitting at the computer, watching tv, reading, home work. I try to pull myself out of it and feel really down. Then I lose myself in my thoughts, and my internal dialogue becomes very circular and negative. I'll pull myself away and either look at myself (hands, arms, legs, body, face in the mirror) or my surroundings (but only one time was it both) and think, "How strange...". Either I am not me, except for the me behind my eyes, detached from the other self that I am, or else I am real, but everything around me is dreamlike, and astonishing in the level of detail.

Any of this sound familiar? What are your triggers?
