<human>: Can you condense the text into a few key points?

I've always been pretty high-energy and lacked a lot of focus. I've always been a terrible student even though I'm fairly intelligent. Most of my problems relating to school have been caused by my inability to sit and focus on anything that doesn't involve a hands-on approach, or immediate gain. I dropped out of college a few years ago because of this, but would like to go back and finish, but It seems impossible with the brain I have now. 

I've only recently realized that I've been a hair-puller since 6th grade. I started pulling out the hair on my head, and now only pull out my beard hair. So much so, that there are patches with little to no hair. The same goes for my nails - although now I just pick a the skin around them, rather than bite my nails. 

This is all very disturbing to me.

A friend of mine offered me a xanex bar, after a long day of combating with my brain's desire to yank out my beard, and a generally feeling of panic, I took a third of the bar before a nice shower. When I got out It was like nothing I had ever, truly, experienced. It worked; I was calm, and I could focus, and felt no desire to pull. If I tried, it felt wrong, and actually hurt to do. 

So reddit, I want to be able to calm down, attend school, be happy, sit still... I have little money, and no insurance, what do I do?
<bot>: I've pulled out my hair, and had a general sense of anxiousness all my life. I took a xanex a few days ago, and I don't want to live like this anymore.
