I'm so sorry to hear this. After my D&C I had a consult with a MFM specialist at Sibley who gave me a whole list of therapists. I chose Kate Marosek:
krmarosek@katemarosek.com and she specializes in termination due to abnormal pregnancy dx, among other things. I bet you could call the Sibley MFM department and they could provide you with the list of therapists even if you are not a patient. I am so so sorry.
