Problem with trusting people

I cant help myself, I literally ditch people and hate them the second I find them threatening to me or do something I dont like. Some of the examples that people do is that they choose not listening and being urdestanding or I see them as they lack empathy. Are people dumb or am I crazy? Why am I so sensitive. Its ruining my job and sometimes I even feel socially anxious outside of work, I have a feeling that my brain judges everything on the negative side too fast. It feels like a really negative life that I dont want anymore.
