How to stop making people uncomfortable

I don’t know what I’m doing wrong but I can genuinely tell that through every social interaction I have with a neurotypical person that I am doing something weird or wrong to make them uncomfortable.

I try to small talk. I try to eye contact but not too much. I try not to play with my hands or tap my feet too much. I try to smile.

How can they ALL think I’m weird so instantly?

At work I’m just awkwardly there. I don’t know what to say to clients or coworkers past “how are you”. They don’t care about my interests and I don’t even know what theirs are.

If anyone has any tips they might think are even slightly useful pls lmk
