Are pills the problem? Or is the problem mental illness?
They might just remove symptoms and not help healing. I crashed while riding my bike and had depression related concussions. It was overwhelming. I took metabolic pills and slept and healed it that way. Took about 4 weeks.
If I had taken psych pills instead, it would have given me a force of stimulation, ie. something to act on others. A sick person is listless and cannot act on others, but dope them with something their vitality comes out strange. They are not healed, they are just pumped up with a dysfunctioning brain.
