I've felt the same concern and still do from time to time. The truth is relationships are a mixed bag and people are all different. Some people really will think you're a socially incompetent weirdo. Other people will wonder if you're thinking that about them. And some people will just find you to be a likeable person.
Ultimately if/when some other people don't like you, well, that doesn't define who you are as a person or that you need to be fixed. It's just not the right fit between you, and that's nobody's fault. It's going to happen, and it only matters as much as you decide it matters. It really doesn't need to matter!
Be yourself, focus less on your perceived shortcomings/insecurities, and focus more on improving other people's day.
