I Have a Fear

So there is a theory thought up by someone I know that I have developed a fear of my home town. It may sound ridiculous to most people but in a way it makes sense. It's not agoraphobia exactly as I can leave my flat and go out to university (a couple of towns over) or go out of town on some kind of adventure without any real thought or emotion, but every time I put my foot on the first train back, or my friend starts to turn the car around to come back, I feel this overwhelming wave of anxiety where all I want to do is scream and hide. I have even been known to have a psychogenic blackout at the thought of returning back here after going out of town, where my entire body and mind gets so overwhelmed with panic it simply shuts down. I makes life so much more difficult.
