Where to start?

BACKGROUND: I have battled with depression since I can remember. I have been on meds for about 8 years and doing so much better. I've tried to get off several times and went into what I call my "black hole". I finally figured out I have to have my meds to survive.

I never even considered ADD. I thought ADD was a hyper kid that could't sit still. I didn't even know adults could have it. About a month ago I was reading a community magazine and I saw an article that cought my eye, The AD/HD Parent. I started to read the article and realized that a lot of it sounded exactly like me. I felt as if they were writing about me. I guess it never occurred to me that there are different types of AD/HD. I guess you could say I would be considered the "Inattentive Type." I just thought that my failing memory and "brain fog" was due to having children. You know, I lost my memory during pregnancy and never got it back. It also doesn't help that I have not worked in 5 years (I am a stay at home mom) so I don't have as much adult interaction. Most of my day consists of having conversation with my 3 and 5 year old. I never could quite put my finger on what was wrong but always knew something just wasn't quite right. Mostly I struggle with making decisions, not huge ones, just your average every day things. It is a major task for me to figure out which errand I'm going to run first; should I pick up the dry cleaning, go to the pharmacy or take a shower. I know it sounds completely crazy but I feel overwhelmed. The same is true with daily house cleaning and taking care of the kids. I also have a horrible time managing my time. It seems I'm always running late. I cannot even get my kids to preschool on time twice a week. They are atleast half an hour late no matter what time I get up. I feel like a horrible mother. I feel so guilty all the time. I can't even keep my house clean or get my bills paid on time.

Silly quirks: (What is wrong with me?)
WARNING: I'm just going to skip from subject to subject.
The odd thing is that I am so **** about some things. My towels have to be folded a certain way, kids toys in a specific place (my daughter's plastic animals are all catagorized in bins according to silly things: farm animals, jungle animals, house pets, etc.) I have to have the mayonaise spread exactly evely and to the crust -- I make the prettiest sandwiches around. Hey, I found something I'm good at! I can also be pretty compulsive, I bought over 100 Cabbage Patch Kids on EBay. Who in their right mind needs that many dolls? I am so forgetful, if it's not written down I forget. I can't go to sleep at a decent hour and when I do I can't stay asleep. I often am bad about interrupting people when talking because if I don't say what I have to say right then I forget. I also jump from one subject to the next for no apparent reason. I will think something and it just pops out of my mouth, it makes sence to me but no one else. I can't talk on the phone while the TV is on, I get to distracted. I have to read things several times because I will start thinking about something else. I am easily frustrated and annoyed. Yesterday I was in Wal-Mart and was so overwhelmed (where do I go first, clothing, shoes, groceries, etc.) that I nearly went back home. I actually felt like I had butterflies in my stomach. I can't stay focused on what I'm doing. I can start doing laundry then switch to the dishes, then to bills, then picking up, but never seem to finish any one of them.

Can anyone point me in the right directin? What type of doctor I should see. I feel embarrased even telling a doctor how messed up I am. I just want to be "NORMAL"
