Ttrpg’s can definitely be used by therapists (e.g.see https://gametogrow.org/ ) but people in general should not underestimate the skill and training professional therapists bring to the table. Just playing an rpg is not therapy.

I’m a forever GM too, and I made this meme referring to a player in my groups. She’s an amazing player and I include her as often as possible. The point of the meme was not really to highlight that people use TTRPGs as a therapy replacement, though I definitely know that some might try that and I agree with you that it’s not a good idea.
