There's an unlying spiritual cause with everybody. Look how many people in that field claiming now that a lot of people are not diagnosed correctly, or haven't been diagnosed yet? The number of people that we assume is "normal" and then all of a sudden do drastic actions? And whatever manifestations coming out of trauma, or of food, or of a birth defect, or of the environment, things that science can't easily "cure" or claim to be purely biological, or purely on emotions, are given names and "treated", with no real sense of clarity of the source.It's because it's not just a physical thing. It's because a lot of these things are manifestations of the spirit, that have an influence on our physical psyche.
In the bible, there is an instance where Jesus healed a blind man. Before that, people asked him if it was his sin or the sin of his parents why he was born blind. Jesus never denied that being a possibility, but clarified that his blindness is there to reveal God's glory to him. (John 9:1-12) There are such things as generational curses, and sin of the land, and sin we put upon ourselves that have an effect on us on a spiritual level and made evident on a physical level, whether mind or body.
The thing with psychiatry is that as long as it doesn't address the spiritual, their tactics will always be like putting a band-aid on a broken blood vessel.That's not to say that we shouldn't be trying to heal physically of things, but idk mainstream stuff always seems to have an agenda behind it that doesn't really care for you to be made whole but keeps you in a cycle of dependency.
