- I have a short span of attention
- I ALWAYS do 2 things at a time

I suppose you mean you can't focus yourself on one thing? Either way, being able to multitask in some form, is great. Just keep attentive so that you don't end up doing a bad job at both. Focus primarily on one first, than the other.

(The thing is, I can't focus on one thing. Note that I am not medicated yet. It's impulsive. I'm just doing another thing while doing one and sometimes I don't even realize it at first!)

- I can't sleep because I always think (I always take an hour or two before I finally sleep)

Go do some heavy sports activity (like martial arts and/or running) and get back like an hour before bedtime (to let the adrenaline cool down). Drink something warm while taking it easy*, like soup or tea, eat, but only a little and something healthy. Nothing with caffeine, that's also most sport drinks and Red Bull and the like.

* Watch some tv, read a book. Don't go sit behind your computer.

(All done. My mind spins a lot. If I try to focus on nothing, I eventually think of something that I can't get out of my mind. Even if I do a lot of sports)

- I am not able to be structured at all

Learn yourself some self-discipline. Make an effort to arrange things in a structured manner.

(True. But the thing is, for exemple, I got an agenda which I bring with me all the time. But, most of the time, I forget about it's existence everytime too. So it's sadly empty.)

- Can't read because I can't focus
- After 30 seconds, my vision gets blur and I am unable to understand fully what people speak from now on.

Are you already on medication? If yes, see about getting the dose reduced.

Don't sit behind the computer for extented time periods. Check with a specialist if you need glasses.

(Not medicated yet. I already have glasses too. Just that my mind seems to shutdown because it's bored. It's kind of odd. It's just that it doesn't want to focus. So sometimes I move my head like I read but in reality, I don't. So when I realize it, I gotta start over)

Geez, I shouldn't have talked about that...now I still don't know what to play!
