It's your job to not feel bad about yourself. When you have good self-esteem you don't take rejection personally. You go 'oh that sucks, oh well' and don't ever really think about it.
If you sit and stew in these feelings, instead of realizing how misguided they are, you are going to hate dating.
Dating is 90% rejection. Get used to it.
I've probably bad like 500+ first dates in my life. The amount of women who reciprocated my interest was about 10%. And none of those relationships ever lasted for more than a few weeks. and only like 5 lasted a year or more.
