Thank you Dr. Fee! I suspect I have ADD but since I'm not hyperactive it was overlooked in my childhood. People close to me know they have to say my name first before they start talking to me or I'm not even going to hear them because I'm either woolgathering or have tuned out my surroundings and am concentrating very hard on what I'm doing.
I had no idea not being able to organize was in any way related to ADD. I'm going to guess that my love for rules and routines and my social awkwardness and discomfort are also tied to ADD. I'll do some research now that I have a starting point to see what other things about me are ADD-related.
Thank you for the links, I'll certainly check them out. This is kind of exciting!
