I know exactly wht you are feelign and going thru. I could ahve read most of your post myself. Although not officially diagnosed with ADD yet (I find out in 2 days) I have all the signs.
It is very frustrating when we are very busy all day long but then at the end of the day you look back and nothing is done. Lots of things gets started but nothing is done. The laundry got to the washer, but never the drier. The tub is clean but not the bathroom floor or sink... etc.
Since I am new to this iI can not help with any advice, but at least you are not alone. And I know there are many others out there jsut like us and you ahve come to the right place to try to find some answers.

Good Luck!
