don't seek approval ... just be yourself
Maybe they see you as too needy ... and don't respect that.
Not sure why you need to get approval from a lot of people. It's much more important to feel good about yourself on your own .. have self-confidence. That will be much healthier and useful in your life.
Because you are putting them in a position of judgement. Seek no one's approval, except your own.
You did state approval, and not love, sure, we all want love, but we can't make people love us, I suggest that you just be yourself, thosr that value you will give their love freely, those that don't...won't, please don't lose sleep over it.
