Hi there, don't let some bad responses discourage you! Others can be weird too and it might not have to anything to do with you. I think it is awesome that you want to be more confident and that you know that it isn't all you. Many misunderstandigs or bad feelings come from misinterpretations or that we think see our own bad image of ourselves reflected in the other person's behaviour. If you are being open and authentic, others will see that. And if you accept yourself more, you might care less or fear that you did something wrong
