Look into nutrition if you'd rather not take psychedelics. I was told by a nutritionist about a study done on nutrition for various mood disorders. They had them take large doses of certain vitamins/minerals and were able to stabilize their moods - I think she said it included things like schizophrenia as well as depression and anxiety. I also read an article about a small study on nutrition for dementia that showed great promise. They too took large doses of certain vitamins and it kept them from declining further (especially in earlier stages). There isn't a lot of money in this for drug companies of course, so I doubt they've managed to get any larger studies done, but it's still very hopeful.
