Have you talked to your doctor about it? If you are here you may have a psych issue. I don't know anything about you. But your doctor should check you out.
I have PTSD and Have same thing happen..doesn't mean you have same thing..only your doc can tell you..but for me - it is normal symptom that should go away as I heal. I was very afraid at first & was taught some safety/ coping mechanisms by my T.
