Trouble sleeping.

I have been having trouble sleeping for a while now. I started sleeping better for a week or 2 but then i began to not be able to again. Some nights im fine, but other nights i just cant seem to take my mind off trying to go to sleep. My mom says i have NO reason at all to stress over going to sleep. I know she's right but its like its stuck in my head or something. I have so many things so help me go to sleep. They probably are helping i just dont know they are. Its like when i go to bed i just want to go to sleep in 5 mintues or less. I used to go out like a light a few days ago but now ive been having trouble. My mom thinks its anxiety witch is probably part of it bc i get tight in the neck and i toss and turn. I used to be horrible and break out crying. I'm not THAT terrible now but still i do have problems every now and then. My mom and i tried to figure out what could be causing stress. Some of the things we came up with might be playing some part in triggering my stress at night. But i remembered something really important. 1 time i had this HORRIBLE nightmare! I woke up and was afraid to go back to sleep. I of course did go back to sleep but after that i did seem a little stiff and kept on thinking about it. But i was wondering how it could of been the nightmare i mean ive been over that for at least a month. But that was when this stress all started. But whats also weird is bc ive been noticing that i go to sleep good for 2 nights and then 1 night i cant go to sleep. and thats happened at least 3 times. If there's any advice that anybody could think of i would really like to know.

This is where all my problems began, I have a cronic (chronic) sleep disorder and was self medicating for years, finally after eye surgery everything came to head.  Now I am on antidepressants, sleeping tablets and seeing a councillor.  Talk to your doctors about it and deal with it now hopefully you will be able to develop a better sleeping habit.  Being anxious about it when you go to bed is the worst thing you can do.  Get some relaxation music or voice overs to guide you into a peaceful sleep and practice breathing exercise.  It all helps and something that I am coming to terms with we create the problem in our own mind.
