In the last minute, he promises to give his "amateur's opinion" of what is really going on in another video.
He says there are other effective solutions. Like cognitive behavioral therapy. For severe mental illness? Maybe as an adjunct...
He hates the medication. OK. The medicine has side effects. Not every medicine will work for every person. It might take several trials to find the right medication. But, there's a risk/benefit analysis that must be done for every person.
He's not a fan of electroconvulsive therapy. It is an invasive procedure and has really bad side effects. It's also a treatment of last resort and is highly effective at remitting depression.
He seems to have an issue with semantics. I personally don't care what you call it. Actually, it's a physiological illness like any other, so the modifier "mental" seems unnecessary and stigmatizing for serious illnesses like bipolar disorder that are visible on brain scans.
Personality disorders might deserve that title a little moreso, but, ultimately an argument over semantics is wasted time in my opinion. As is arguing over illnesses and categories for the DSM.
Yes, the suffering is real. He admits this, yet has no answer for it, likely because he is no expert, as he admits.
So, why is he talking?
