This is it, and it's really a broader issue with online communities for a lot of professional services in general, whether it be mental healthcare or medicine or legal services, etc. I'd argue it's not just difficult to give real or helpful advice through these communities, but also irresponsible and potentially negligent, and that's not even going into professional ethics issues like patient confidentiality or attorney client privilege or a whole host of other ethical concerns.

Professional services generally fall into a bucket of "above the internet's pay grade." You really need a licensed professional, but a licensed professional isn't going to be distributing advice over a community forum, both because it's typically a paid service and because they really can't even if they wanted to.

Options are at least expanding for remote professional services, and I'd recommend looking into those options if you need specific help. I'm also not saying communities are bad and they can be great for general support and community, but they're not a replacement for licensed professional services when those services are needed.
