Have you talked to a therapist about the fall? You could be experiencing PTSD from the event. If it is PTSD, talking about it will make the symptoms worse in the short run but might help them fade with time. My attempt caused me a lot of trauma and I had a lot of sudden urges, anxiety, flashbacks, etc but now, four years later--all of that seems to be gone. It was intense for a couple of years. When you are in an accident, you go into shock (block out the emotions during the event in order to slow your body down and stay alive) but then, eventually, I think your body wants to process the event/feel the emotions you blocked out so you feel the fear/anxiety intensely for a while and that process causes a lot of involuntary physical responses. For example, I would get a lot of intense panic attacks for a while and would lose time (for example, be distracted out of the blue while driving, not remembering how I got from Point A to B because I would think of the event at inopportune times). If you are experiencing PTSD, it might get a little better eventually but I do think it is important to talk about it. I am glad you are talking about it here!
