Loser with no social skills

I’ve always been the socially anxious quiet timid kid throughout all of school, even suspecting im on the spectrum or neurodivergent.

But socializing has always been puzzling for me, i never got the hang of it and it never came naturally to me. So overall im extremely awkward, quiet and standoffish.

I have a difficulty making friends because at some point i feel like i become insufferable and tiring. Like people lose interest in me, im too boring, serious, and awkward.

People take interest in me initially and treat me like any other human, but once they see more and more of how i am, i feel like that interest dies pretty fast..

I’m not funny, i dont have a charming personality, half the time i literally have nothing to say, like absolutely nothing. I give off the impression of an airhead, and i can tell some people think im an idiot. Because of how i miss social cues.

My social skills impede me greatly and i dont know what to do. I’ve already tried to improve them but at this point i feel like i will never be able to form connection and make friends. Not to mention how its 2x worse with women too..

Advice?
