Curious, is your PCP also at Mass General Brigham? Super helpful rec, but might not be an option otherwise :/

(I was recently diagnosed by a psychologist in a different system, but they could only give me a giant list of places to try calling for a psych appointment. I instead tried calling a Mass General Brigham location that would have been very convenient for me, but the scheduling staff sounded offended I would even ask without having a PCP at MGB despite 5 of 5 psychiatrists showing as "accepting new patients" online.)
