I understand your situation completely. I also have extreme insomnia and I'm sick all the time. I mean, almost every morning I wake up and I feel like a giant ball of crap, and then when I do get sick, I'm sick for weeks.

I graduated, but most of my teachers and friends believed I was just being a drama queen until they actually saw me getting sick, and some of them still didn't believe me.

I really don't have any friends either, it seems they all went away in the last couple months, my best friend is my boyfriend.

My mom abandoned me back in December when I was 17 and now I live with one of my old friends' family..

Thankfully they actually accept the fact that I'm sick a lot, and that sleeping medicine doesn't work...

It will get better, just hang in there and see if you can find a better doctor!
