I don't think it's fair to use the experience of people in this subreddit as a representation of speech therapy. As I indicated above, I suspect most people who achieved fluency through therapy aren't frequenting this sub. We're likely running up against a type of survivorship bias when we examine the experiences of the people here. I agree that it's devastating to seek treatment and not make any progress. But I hate seeing people give up. Or tell people that it's hopeless (not talking about OP. It's just a frequent sentiment in this sub.)
