When I have been in the place you are, and I'm pretty sure most of us have been at one time or another, do something to distract yourself until it passes, b/c it will, trust me.
I had one of the same waves hit on Friday night. I didn't imagine I would surface on the other side. I did though, & you will too. Know that. Think of it as a set of waves, one coming right after another holding you down. There is always a period afterwards, in between, to catch your breath.
