I would try some exercises to calm yourself down for at least a few minutes so you can make a decision. Like write down on a piece of a paper for a few minutes what you're feeling, then throw it away. See if something like that helps. I think this is a great oppertunity. I found my summer start really helpful, plus you're getting in to a T14 outside of LA, just like you wanted. Like someone else said, two weeks is a lot of time. But make sure you try to calm down a bit before making any sort of decision.
