Well, for one, I am truly sorry you are going through this - I have been through it and it was sheer hell! Your doctor does not seem sensitive, much less "informed".

Sleep deprivation is critical - you have already mentioned many of the symptoms.

I suffered 7 days with about 3 hours scattered sleep and I ended up hospitilized, not waking up for another 7 days! (Medication assisted).

My most immediate recommendation to you would be to change doctors.

There is help out there!
