I get paranoid at night and it is very hard to fall asleep?

I have always been afraid of the dark my whole life and now it is getting much worse to the point where it is very difficult to fall asleep. I'm pretty embarrassed about being a 17 year old who is so afraid of the dark. I have this paranoia that haunts me every night and it frustrates the hell out of me. I always feel like something is in the room with me and I can only fall asleep if I have the t.v. on or music playing from my computer. The paranoia just keeps getting worse. I also have some anxiety problems which I think may contribute... someone please help. This problem is starting to really affect me and frustrate me to the point of almost no sleep at all!
