Very weird reaction to knock at the door and unknown phone calls?
When there is a knock at the door whether I'm in my dorm or at home in my bedroom I jump up and frantically go to look, my heart races, my arms become weak and numb and if the knock is loud and aggressive I will even shake and it usually takes 20-30 minutes to subside. When I get an unknown phone call even when my phone is on silent and it just pops up, the same happens just not as severe but those seem to be the only two triggers. For some reason I feel like I am about to get in trouble or humiliated when I open the door. I have no idea why.
I have no idea where this stems from.
