What kind of things have happened close by? The symptoms you are describing sound a lot like PTSD to me. Look it up under disorders (on the menu bar above), and see if it sounds familiar to you. I really would suggest therapy. Even though money is tight, there are usually ways to get therapy on a sliding fee scale at a low cost.
