It's complex, can be multiple differing sources/causes individually or compounding, and what most of the world does is to follow a protocol of experimentation and practices for people to go through on their own to see what alleviates different dis-ease states - or where at least there is a net benefit found/experienced. The "solution" of psychiatry to deal with mental health IMHO is pure regulatory capture, a cheap, lazy solution requiring little to no skill or deeper understanding or experience by the administrator - and providing a recurring revenue model that seems to most often cause dependance.
