Socially Incompetent

Hi,

I am socially incompetent. I think I have ADHD and social anxiety but I’m not 100% sure. I keep getting told by my family and others, that I am selfish, and I really want to fix that, but I don’t know how. my friends have also told me I’m emotionally draining or tiring and I really want to fix that too. but again, I don’t know how. even my best friend says that and she does like hanging out with me. She just also needs a pretty big break and she’s an extrovert. I’m also terrified of everyone leaving if I say the wrong thing or annoy them. Friends of also told me that I am annoying them, especially because of how clingy I am. I think I probably need reassurance but I really don’t want to ask for it because that would be annoying and what if they say they don’t want to be there. I’m also terrible at social cues and never say the right thing or do the right thing, but I’m incredibly observant and tend to notice things I guess no one ever does, which weirds them out because of how much I know. I’m a very fairy touch oriented person. I also frequently overthink things. I never know if what I’m doing is too much or too little. I know I’m doing these things, but people won’t tell me what I’m doing wrong to be nice or because they don’t want to offend me, but it’s also hurting relationships. I really need advice on improving my friendships and would like to stop being such a burden.
