Help with writing/typing skills

[blanky!]

I have this huge thing that I have to get off of my mind, right now.

I hate having to pause every 2-3 words to try and organize my ideas.
I hate having to retype everything due to extreme OCD about how I word myself.
I hate having to write essays, for this reason, because then I'll have to waste every minute trying to figure out which word choice is the best.
I hate having to organize my ideas because I can't do them fast enough in my head, and then I see everyone else typing up their posts/paragraphs in an instant. It makes me wonder what's wrong with me.

there, i did it again. i had to pause when others probably didn't have to.

I tried to type this post up with minimal thought whatsoever, but usually typing up even one line can take a few minutes if I'm really picky. This runs in my family, too -- it makes me so frustrated seeing my parent pore over every single detail of a certain work e-mail message.
I don't know why but I just keep blanking everytime I try to think of ideas (no pun intended lol).
Any way to help?
