I don't but my youngest boy does. It is all I can do to help him not panic when trying to make plans for things.

He has always been like that. We have a special thing we say to each other. "Wooosaaaaa" It's from some movie he saw and we use it when one of us needs to chill out.

But it doesn't matter if it is something that is a day away or 5 months the panic is the same. He will agonize for months over an event.
