Am I the only one that is terribly afraid that something bad is gonna happen suddenly to me/my family?

It’s probably also because of my childhood but Everytime I leave the house there’s this fear that my mom or my cat is going to suddenly die/someone is going to kill them/someone will sa me or just assault in general. It makes me so nervous and sometimes I cry just because of the thought. It happens everyday and it’s getting really tiring after some years.
