I don’t want to throw the word enshitiffication around, especially when I’m not sure if I can spell it, but the platforms that people jump ship to when that happens are probably especially vulnerable to people jumping ship again.

There’s a book called Tabletop Role-playing Therapy: A Guide for the Clinician Game Master by Dr Megan A. Connel that’s a really standout resource about this, she appeared on the official D&D podcast a year or so ago talking about it.
I’d say that this is more a resource for therapists to use TTRPGs than it is for DMs to act as therapists for their players. There’s a fine line between accommodating your players’ preferences and needs and providing unwanted therapy; if you want to actually put any therapy techniques into your game, ask your players approval first.
