if you feel vulnerable as an adult, what can you do about it

basically because of my anxiety, paranoia and mental problems, i feel quite vulnerable in society and fearful of being taken advantaged of by shady types.

it does make me angry, but i can't exactly go berserk at people because i feel vulnerable, because that's against the law.


i do have a vicious temper that i try to control as well.


so what can i do?
