Everyone is against me [Vent]

It feels like everyone close to me is against me, they put up a good front but I know the truth. They all talk shit about me behind my back. It could just be because my brain see's others as a threat or idk. I wish I didn't have to interact with people. I truly feel ok when I'm alone nowadays.
Like why do they think this is ok/funny? it's not to me. Why must they feel the need to do this? I know I just bring pain and suffering to others just by existing, but come on.
