So confused! Just feel like crying!!!

Hello all!! I really need help!

I know it is a BIG message, but would be great some imputs!!!

I am SOOOO FRUSTRATED!

I am a 27yo woman from Brazil. First let me say I am a smart person. I learned English by myself, in 2 years, without ever going to an English school. Once I decided to go college in here, I was admitted direct to the educational program and not to ESL.

So WHY DO I FEEL SOOOO DUMB? I feel like crying.

This is what happens. I need to take the board exams. And I can't study!!!!

Every time I sit to study I feel either ELECTRIC (as if there was extra energy in my body and I wanted to yell, and I cant sit still so much energy I feel), or I feel like I am sooo tired that I could sleep (even if I just woke up and if I was to lay down in bed I wouldn't feel sleepy and I would actually feel awake).

In School I could never sit still for too much time. I would get that electric feeling. up to right school, I would just draw or make lists, write things I planned on doing to pass the time and calm down... In college, I would live class and go for walks... or drawn and write too. Than, I would copy my friends notes and wake up the day before the test at 3am and study like a crazy. Not sure if it is because at that time I feel so in peace with myself or if is because I know I cant procrastinate anymore, but I will concentrate 100%, and will usually have an A in the test. (I memorize sooo easy when I do it).

This is how I managed to ended up college with a great GPA.

Problem is, now I need to study to my boards and I cant sit still for long enough to learn something. Or I feel frustrated and want to give up. I need help!!!

Are there thecniques I can use? Why can't I sit still and learn? AM I lazy? There will be times when I will sit down and study for 2 hours in a roll and it is awesome and I feel so good. But I have sooo much to study. I can't afford to study only 2 hours on a day and even in my best days, it is the most I can do.

Do you think I have a learning disability? What should I do?

In between: I don't have insurance or money for evaluation (in the college close to my home they charge 2000 in testings).

I could use some tips though...

If it was the case, where should I go to evaluation? regular physician? psychiatric? Does insurance covers these kind of evaluation???

Can I find more affective study techniques for me to use while studying in the between (I wont have insurance until August 1st)
