I tend to be closed off to people and am socially awkward which makes having close friends really hard. So maybe what you are unintentionally projecting to the people around you is that of someone who is hard to communicate with or some other characteristic with a negative denotation.

I am not trying to accuse you of anything or saying this your fault, just trying to gove you something to think about.

Please message me if you want to talk about this more :-)
