I agree that text based therapy does leave a lot of room for potential error. But if you’re aware of this, and of what is “your stuff” and the therapist’s stuff, it could be helpful, imo. Just be sure to stop the therapy if the therapist really isn’t understanding.

I think it depends on the therapist, you could find a great online therapist and a very sub optimal face to face therapist who is either clueless or worse
