I've had my share of experience with mental health professionals & my opinion is pretty strongly mixed. My outpatient therapy team is a big part of the reason I survived anorexia during undergrad; but on the other hand, they were a bunch of hardcore christians [1] who definitely held me back from expressing my gender & romantic identities for many years. Glad not to be dead tho, so I'm thankful for em on the whole.
When I decided it was time for gender-related therapy, I was *very* careful to choose someone extremely, visibly LGBT friendly. The one I went with was actually transmasc!
[1] one of them was literally a missionary; and the other led a program for "turning boys into Christian men" that I was *thankfully* too old for
addendum: holy cow that is quite a cw
