Hey there, cool- I hope your day became less overwhelming as the hours passed. Excellent that you have the appointment on Friday.
IP is something of a time out, for sure. And then it has its own stresses, too. One IP I did provided a rest that I desperately needed. The other 2 were a waste of time/somewhat traumatic.
I'm all for calling your pdoc (if you haven't already). I've found that when my mind is turning to go and turning to stay to an extreme, a med intervention can be truly helpful.
Keep us posted.
