Welcome, stew. What you described definately sounds like panic attacks. You've had a lot happened lately and stress sometimes makes it easier to have these attacks. Seeing a doctor is the step in the right direction. Is this a family doctor or a specialist?

You've spoke of asking unanswerable questions, and the need to have answers for everything sounds like you've got anxiety too.

I hope your appointment will go well. Please let me know how it went. Good luck.
