I find this... frustrating to read, at the least. This post assumes that all depression is a _lack_ of something external to the body. Or that depression is simply a chemical imbalance. It takes no accounting of physical deficiencies that can _never_ be cured and require a lifetime of maintenance, of which Ketamine can be (literally) lifesaving.
The post is irresponsible. No one should be thinking that some sort of "transcendence" will solve their issue, or that is what their problem is.
Always discuss treatment with a psychiatrist.
