Baby steps. Take one day at a time. In the mean time there are some things you can do to make your exit a bit easier.
Start making friends outside of the org. so that when you do leave you will have a support system.
See if you can take a course of some sort that will better your education.
Even though you feel suck right now this is not going to be your lot in life and things do change. Sometimes very slowly but as longer you are pro active and take charge you'll be ok.
