debbie, please don't give up.
i know how hard it is to get conflicting medical reports and opinions.
it's also hard to have to wait for a dx to finally become evident.

i'd make another appt with the DR and have him explain why his NP said what she said.

if you're not satisfied consider getting another opinion.
take a break if you need. start the antidepressants and give it a few wks to take hold. see how you feel. but, your sx's certainly don't sound like depression.

take care and keep us posted.
