Mental health therapist who knows long covid?

Long COVID, being forced to close my consultancy of 44 years because of it, having a 78th birthday, too many friends leaving the area -- all the things that can "trigger" a mental health issue. Finding anyone who does the usual therapy AND knows enough about long COVID to understand the struggles of finding help is , so far, impossible. And yes, I have other criteria like location and a few more.

How are any others screening for mental health help for knowledge of LC/PC OR have you found mental health therapists at least empathetic to the issues? I'm in DC and need someone in the District and not in VA or MD.

Thanks.
