Sleepless

I haven't been so great lately... I lack sleep, I have exams soon, I can't get a job anywhere, my parents are nagging me on what I'm going to do next term for school, they want me to get into a BA program and I don't know what I want...
Honestly sleep is the only thing I can think of now... It's been more than three days since I last slept. I'm exhausted and dying for some sleep but I can't. As soon as I lay still and calm down I just start remembering how alone I am, how I feel about everything going on in my life, then I start thinking of all the things I should've done differently, and it's like I get this panic attack or something... I don't know what it is, but I don't like it.
I've tried everything fall asleep... I tried music, I tried reading a school book, I tried exhausting myself I went running for a couple of hours, I cleaned my apartment, I tried reading Qura'an, and I tried sleeping pills... Nothing! It's bad cause the more I'm awake the more I think about stupid mistakes I've done, I think of more problems I've created for the people I care about, the more I'm awake the more I want to eat, and the more I'm awake the more I'm exhausted the less I want to get out of bed/off the couch! I feel like the no sleep is going to drive me insane!
