Maybe your pdoc also feels you are taking some very potent meds, too?
Maybe her extra concern IS founded? Maybe she's very concerned by something you'd said or had done when unstable? She knows you quite well by now.
Maybe her current requests are "right on target" for all you have been going through?

As for an NP's abilities to fully manage your meds, that may depend upon the NP, of course. Some are more skilled and intuitive than others.

Have you asked WHY she wants Jeff to help you with your meds?

You've mentioned Jeff has some respiratory symptoms. How is he doing?

I hope for the best for you, my friend!
