Essays vs. ADD

I have, through a number of stupid online tests, diagnosed myself with ADD. 
And I wish I could say I was kidding, wish I could say it's a joke, wish I could say I'm over exaggerating, but I am not. I have, several times, tried to explain my situation to my mum, but the woman says, "You're too smart for that." I doubt I'm the only one that can say this makes no sense. I have come to learn that people with ADD and ADHD are experts at math, for whatever reason. Throughout my childhood I have been placed in advanced math classes. Coincidence? I think not. 
But the fact that I do well with arithmetic means next to nothing. 
Time for elaboration:
My mind is ALWAYS wandering. Especially from things that I find uninteresting or difficult.
I have a VERY difficult time reading material that isn't interesting fairly easy.
Especially in groups, it's hard for me to stay focused on what is being said in conversations.
Do I have a quick temper? Yes. And I forgive and forget almost instantly- because I can't at all help it.
I can get annoyed by the strangest, littlest things.
I say things without thinking, and as soon as I speak, I regret having said anything at all. The only excuse I have come up with for this is that I talk just to make a sound, because half the time, I don't even mean what I say.
My moods have their highs, and their lows.
I have THE MOST DIFFICULT TIME planning in what order to do a series of tasks or activites. I'm horrible at it. 
I answer questions before the question is fully asked. This actually happens quite frequently. I usually say "no" or ask "what?" instantly. 
I'm working on many many projects currently, and none are getting done.
There is a lot of static and chatter in my head, like a tv has all the channels on. QQQWWWIIISHHHHHHHHHHHHHHHHHHH.
My mind gets ssssoooo cluttered, that it literally is hard for me to function. It honestly keeps me up at night; I have trouble sleeping because of it.
My thoughts bounce around in my mind like a ball in a pinball machine.
I NEVER STOP DAYDREAMING... Sometimes, that's all I do, AND I AM UNABLE TO DO ANYTHING AT ALL BECAUSE OF IT.
I am wholly distressed by the disorganized way my brain works.
I wish I could get help with this, because I believe my life could be SO MUCH BETTER if I could get my head on straight. Honestly, I feel like a piece of shit filler-to-the-world of a person, and am extremely terrified that I will never make a move to accomplish my goals. That I'm just floating along with no real destination except what is given to me, and nothing more. I (of course) dream bigger than myself. It's that damn daydreaming. Just the thought of clear thinking, to be more determined and set straight... The mere  thought excites me. 
Today, I stared at the computer screen for over an hour, trying to think of what words to use in my essay, on a damn book I haven't even read half of, and I became so frustrated with not knowing what the hell to put, because I cannot stay focused for the life of me. It really upsets me. I should be working on it know, but I'm still lost for words. Still worth a try


Au revoir, les amis.(:
