Your sick kid ("sick" being either real or perceived by you) got inconvenient so you dumped the kid off at "One Flew Over the Cuckoo's Nest" and even if you didn't know in the past that it was statistically worse for the kid than care in the community or, if the kid really was sick, worse than appropriate treatment options, you have no excuse for not knowing now.
You're a selfish, sad individual who is desperately trying to masquerade as a decent human being, in this case by trying to convince others to do the same rotten, selfish thing you did.
Parents should get appropriate care for their kids when their kids get sick, or therapy if their kids need it.
Parents should not dump their especially vulnerable kids off in a facility that is a bad choice just because it's a pain in the ass to personally care for and raise a needy kid.
You're as bad as the Lexus parents who work seventy plus hours a week and dump their kids off on a succession of au pairs and nannies.
Or the pet owners who dump their pregnant dog off at the pound so they don't have to deal with the litter.
You did a rotten thing. Everybody does something rotten sometime. But instead of owning up and taking responsibility, you keep frantically trying to justify what you did. No wonder your poor kid had problems.
