eh... I use to to feel awful being rejected, and go into isolation to ponder what the hell I did wrong.
Now I find myself getting mad and fustrated that the other person either doesn't understand, or that they really think me and my opinion is not worth the trouble in dealing.
I feel horrible, so in return I start treating others horribly...then go hide somewhere to avoid rebuttals.
So I guess your not alone in the situation of rejection, and that is a type of relief in itself.
Sorry this post wasn't much of a help as it was an personal soap box...
