should you be bothered if many people don't like you and are against you

that's how i feel at times, i'm quite a solitary antisocial figure, there are lots of people i don't like...but i don't broadcast that i just mind my own business and are quiet in real life...but at times i think people are standoffish and unfriendly towards me in real life..and i feel avoided too...and i think people are against me.

i have no real proof people are against me but its just a feeling and vibe i get, like people are waiting for me to kick off and lose my temper, so they can attack me and have me outcasted....maybe this is all in my head.

anyway how should i react to it?
