I Want More Self-confidence

I know that Iam more than my size and I wish I just simply didn't care .. I'm not that big but regardless if I lose weight I know it isn't all going to come off at once.. it's just that when it comes to guys I'm afraid of being rejected .. I haven't been yet .. but you never know idk I just don't want to care I just want to be happy and be okay with people not liking me . Ughh btw I have a date later on Today I'm nervous
