Anyone else have terrible anxiety of being shot

This wasnt my main reason for becoming a shut in but it definitely played a big part in it and I was curious if anyone experiences the same feelings since i’ve never seen anyone talking about it. I quit going to public school because it got so bad on top of many other reasons. When i would go in public i could not stop thinking about someone just pulling a gun and shooting into the crowd. To the point where id dissociate. Id always be thinking of where id run/hide or what id do. No matter where i go Ill always look for an exit. It gets worse in certain places aswell.. i see all these bodycam videos, whether it be at the mall, grocery store, a church I always thought about them when id be out in public. These things like shootings and stabbings fuck me up so bad i dont even want to go in public anymore Its not even just outside but in my own home.. Im always checking my windows thinking im hearing things. I dont even live in a dangerous area and i still cant get it out of my head. I dont even necessarily care to be alive but i still have this fear. Its alot worse than i can describe and I know most people fear this but has anybody else completely stopped going out in public bc of it? And im sry if this is stupid. I dont usually post, Just looking for someone to relate
