If course there isn't an objective "correct" on this matter. What is too much for one person is fine for another, but this thread was started by you saying 2 people had told you you were overthinking. I'm going to presume this is in a relatively short amount of time, not over your lifetime.
Now, 2, can just be unlucky, but if, when you are trying to garner opinions on some tiny detail, that no-one is going to notice, you get told 3, or 4, or 8 times that no-one will care or even notice, and you are over thinking this level of detail, then would there come a point when you might begin to think there is a sort of a broad 'norm' and that you are without it ?
Whether that is a problem or not for you will depend on you.
Humans are societal, and we live by cultural norms. Some people are happy, and even proud to live outside of those norms; Some people aren't aware the way they act or speak is considered difficult to live with, by others;
If you (I mean 'a person', not you particularly) is either asking others' opinions, or giving so much detail of their thought process that it is really annoying to those around them, then fewer and fewer people will want to spend time with them. For me, it is a bit like if you have a friend with BO. It's a very, very difficult conversation to have, and will likely upset them if you let them know, BUT, in the long term, them doing something about that which makes it difficult for them to retain friends, will mean they end up with more people enjoying their company, so the person benefits by being told.
Now, if there is a person who irritates the heck out of everybody by not just being able to have a chat on a normal social level, would they want to know this is why people edge away from them in a social situation , or not ?
I don't know. I guess it would depend on each individual person as to whether they value friendships and company more, or value picking over every tiny detail more. However, if they know, they can begin to work towards making that choice. If they don't, they can't.
