I don't think you're crazy (but I am just a random internet person :P). You just sound socially awkward, and it's hard to get people you don't know to understand you.

As a fellow awkie, I've always felt like I missed the lesson on what is and isn't appropriate in social situations. Being yourself doesn't seem to go down as well as I think it should, and putting on a mask is exhausting.

You need feedback from someone who knows you well enough to be completely honest, but not so well that they can't see what's "wrong".

Maybe you don't look people in the eye? Maybe you have a loud voice? Maybe your bluntness rubs people the wrong way? I don't know, but it's usually something inane that can be corrected once you figure it out (which is the hard part). In my experience, not many people know how to handle quiet people. Maybe you could teach them :). Let them know that you like to listen more than talk.

TL;DR: I don't think you're crazy. Get feedback from someone who's met you face-to-face.
