You are right about the vicious cycle. My suggestion would be to first see your doc to either treat or eliminate the possibility of a medical or psychiatric issue such as a stress or anxiety disorder. These are medically treatable.
But in the absence of a medical disorder, you can look at nonmedical issues that need to be addressed for sleep improvement. These typically involve sleep habits (including sleep hygiene and sleep restriction) and excessive worry about sleep (the kind that you are expressing). These are all treatable through a comprehensive CBT-based sleep training program.
Like curiousmountain, I also did this self-help, and the methods do work for most people. This will help you determine your optimal sleep schedule as well as put a stop to the negative and aggravating thought patterns that are keeping you up.
Good luck.
