Would you be willing to try exposure therapy by yourself? Allowing yourself to think whatever thoughts come to mind, no matter how awful they may be to experience. It is torture at first but eventually you will come to realize that these thoughts are no different than any other thoughts. Just sit in a relaxing place or lay down on your bed, close your eyes, focus on breathing deeply and let whatever thoughts flow by like a river. Maybe you won't be able to do it long for the first time, that's OK. Keep at it. Also please feel free to PM me if you want to talk/vent.
