Hello northforkmom, and happy birthday to you!
I'm in my mid-40s, too, and struggling with treatment-resistant depression, have been for more than 10 years. I've tried many medications, none of which have worked, been hospitalized twice, neither of which times helped, and been to several therapists. So, I feel your pain.
I've never tried a psychopharmacologist, and I'm not near NYC, so I don't have any help to offer in that regard.
I hope you are able to find the help you need. NYC must be chock-full of resources.
Good luck to you, and I hope you feel better soon!
