does anyone else get scared to ride public transportation?

I feel like as of more recent with the uncertainties and unsafeties of the world as we grow and carry on i am becoming increasingly scared of riding the public transportation. I've recently lost my car due to an accident and have began having to ride the bus every day. I'm relatively tall and intimidating (parents can confirm) yet even so I still find myself constantly watching my back and being scared of any hostile junkies or degenerates. I don't feel safe if ever outside of my own home. I've began concealed carrying every time I've ridden the bus since I've started and even then I don't feel safe, as if something could happen at any second, was just wondering if anyone feels the same way. I live in the south if anyone is curious
