If it comes from past experience than it is not a paranoia as such.

For example, there is a difference if a suburban Westie is paranoid about government and police being after them and if the same fear is experienced by a political refugee.

Psychiatry has it's ways to make you feel crazy. Don't want to take their pills? Must be because you NEED them and are sick. Think you are more or less okay? Must be because you ill. Distrustful of the field and doctors? Must be your illness talking. Kinda mind****y, if you ask me.

I'd advice you to seek help outside of the field as well. It is there.
