Sweetie, you just described what I do everyday. LOL I had to laugh when I read this, and I'm NOT making fun of you.
I also have major depressive disorder (clinical depression) and I was diagnosed years ago. I'm NOT on as many meds as you are. I'm a chronic pain patient, so I'm on OpanaER 40mg twice a day, Lyrica 75mg twice a day, Topamax 200mg twice a day, and Prozac 20mg a day, plus Zocor (can't remember the dose) for cholesterol.
For ME I don't think it's ADD -- I think I'm just flaky. LOL And it MIGHT be from the OpanaER, but I don't think so. I've always been like this to some extent so maybe it IS ADD, I don't know. My head always has racing thoughts in it, but nothing makes alot of sense, so I don't pay much attention to it.

I just get sidetracked. LOL
You could talk to your therapist about it -- perhaps figure it out. I always did well in school, tho -- so I don't know.
Take care my friend. I hope you don't have ADD -- you don't need any more medications.

God bless and please take care. Hugs, Lee
