Rejection hurts your ego but if you don't blame yourself for it, it will pass.
It hurts, and leaves you feeling a sense of incompleteness
Like someone just crapped on your heart.
it makes you feel like ****, but once it happens enough it pretty much stops bothering you. at least that's what happened for me, i'm sure other people might have a harder or easier time getting used to it.
It does hurt when you realise that it was 100% each way.
