I feel I’ve given too much power to others and they’ve picked up on it in that I let others shame me into hiding some good qualities about myself as to not appear arrogant or cocky to others. I often find myself not knowing how to act and looking awkward because of this. So where is the line, generally speaking, when it comes to being confident instead of arrogant or cocky, and how do I know if I need to dial it back because my head is getting too big for my shoulders or the person/people I am interacting with or around me is/are just insecure and are just trying to shame me because of that reason?

I know it is a broad question without any specific scenarios, but does anybody on here have any rules of thumb or guidelines to follow to determine this?
