LimeAid13, welcome to Psych Central! Obviously I don't know you very well, but I do know that frustration can lead to anger. I am thinking that's what's happening to you. However, you definitely need to be patient about the grad-school position. If you were to contact them in anger, then I think you could kiss your prospects good-bye.

Keep applying to other places if this one does not work out.

And, yes, I have had a few times where I would have liked to tell the whole world off.
