Jason,
I have this problem, too. Trouble is, I start too many things at once and try to complete them all within a day. I end up stopping on one task and jumping to the next, intending to complete them all by the end of the day. Needless to say, I never complete them all.
I recently realized, with the help of my self trained therapist I call my wife, that I am always busy because this way something is always occupying my thoughts and time, and therefore I don't think about SA issues. I am almost sure this is true. An avoidance problem I use, and it keeps me so busy until I finish very little within the time frame I want.
I also have a terrible short term memory and end up with a pocket full of notes at the end of each day. I've had to do this since my late teens. Yeah, I have avoidance and denial issues, but I'm trying to work on 'em.
Maybe that is your problem too, Jason. Trying to fill your mind and life with too many tasks all day long in order to keep the bad thoughts from creeping in. Works for me, but it's awfully frustrating.
Try pacing yourself. Make a list of things you want to complete in a day and allow yourself a realistic amount of time to complete them. If there are too many tasks, work on the rest tomorrow.
