Why the hell do you feel bad for a rejection? You actually went for it man, that's awesome! So what if the girls made the mistake of leaving you, that's their loss! Don't view this as a rejection at all, you should see it as a lesson.
That you got rejected means that there's room for improvement, and this happens to everyone, it's the ONLY way to really learn!
And ofcourse, I can understand how you feel about rejection given that you haven't developed the right mindset yet. But my best advice is: Keep at it! Don't let them bring you down if their stupid enough to reject you. Keep practising and keep getting rejected. As said before, it's the only way to get better
