<human>: I'm 20 years old and I feel like I'm dying.  Over the past couple of years I've had some irritating aches and pains and no health insurance.  Currently, I have health insurance through my school, but I won't have any money to spare (at all) until next month at the earliest.  I hate doing these kinds of posts, but if ANYONE has ANY idea how serious these symptoms are it'd be great.  I don't know if I just have a low tolerance for the average amount of pain, or if my limbs are going to fall off.

Things you should know:

I'm bulimic. It's not as bad as it was and I'm now at a healthy weight but I still throw up everyday

I'm a vegetarian

I get faint rather frequently, but it doesn't coincide with my eating habits

My hands go numb.  About a year ago (when I was a cashier) this would be an every night/morning occurrence.  They would tingle and cramp.  Recently, it feels like my joints are scraping together in a really painful way.  

As I'm typing this, my right arm is throbbing like I might have worked out (but I haven't.)  It feels like the blood flow is messed up somehow and I have to hold it up to keep it a dull ache

It's gotten to be relatively cold here and my hands have been turning blue... really blue.

I banged my head pretty bad last week and have been having headaches ever since 

I had brown/black discharge for about a week before starting a VERY heavy period.

I generally feel very weak.  I tried getting on a ladder tonight and couldn't stand for more than a minute before having to sit down.

HELP! I don't know if these are commonplace things that I'm blowing out of proportion, or I'm in serious trouble health-wise.  I know, I know: clinics.... blah blah blah... doctor... but we don't have much in my area and my car is currently not working.

Can you condense the text into a few key points?
<bot>: I feel weak and achy, but can't go to the doctor.  Am I being a hypochondriac?
