I know how you feel. I'm trying to get past this stage too and its pretty difficult.
I think when you're starting to feel like shit is just what YOU think she should think of you. (This sentence is weird

) If you think you are a shit, you are a shit.
I know its really difficult but its impossible to get everybody to love us. So if someone likes you, cool but if somebody doesnt... then f**k her or him. They pass on a wonderful chance to know a great individual.
