I feel like shit

I have been crying and my head is killing me. I had all week to study for my final and I could barely do it. I have felt horribly depressed and I haven't seen anyone really. I never really leave the house and it wasn't bothering me but I feel so alone and I don't feel connected to anyone and I should be asleep but I am scared to sleep. I thought I was over that but it had been bad the past few days. I stay up until I can't take it anymore and then pass out. I'm having a lot of dreams that I have had before and they are real odd and don't make any sense. I don't want to sleep! It's scary! I should feel proud I am almost done with my class and I am taking my medication and I am trying, it is just so hard. I wish I knew what to do. I'm going to read and hope that sleeping somehow gets easier
