I was diagnosed with schizoaffective disorder back in 2004-2005. I first started showing symptoms around 2002-2003. I also spent a lot of time on psychiatric medication, in addition to having absolutely no eating habits (worse than poor). After being stabilized on medication, and arguing with the doctors, they decided to change my medication anyways. After that nothing worked, and I had to make my own decision to either find a way to manage my 'symptoms' or leave myself under the care of the newest experimental medication for the rest of my life. People have seen and heard things that others don't since the beginning of time. I found that educating myself about a large variety of topics, including; religion, nutrition, exercise, quantum mechanics, string theory, addiction (not only related to alcohol/drugs), and the whole time searching for my own beliefs regarding life, the universe, and everything.
Raw vegan worked well for me, but I began to lose too much weight. Cutting back on the amount of meat I eat, learning about the natural order of plants and animals, and incorporating extra fruits, vegetables, and herbs, into my everyday life has made a huge change. I don't think there are too many people who will disagree with you or me, that there is poison in the food. A very interesting movie I can recommend, is called 'Branded'. There are also many documentaries that present a large amount of information, while still being somewhat entertaining.
Few people manifest dis-ease in the way that we do. I believe it has to do with a combination of factors, as all dis-ease stems from. I'm sure you can agree, that we are not only physically sick, but spiritually sick as well. I can assure you that life without medication is possible. Take your time, move slowly, and be safe. Just because a practice is 'spiritual' does not always mean it is safe. The only difference between medicine and poison is dosage.
edit: After learning more, and adjusting my diet and daily hygiene, exercise, and prayer practices, I have moved back into a meatless diet, and I have gained more muscle and energy. I hope you and others read this, because I remember a time when I believed there was no hope at all, medicated or not. If you have any questions I would be happy to answer them. Nowadays, people trust me to babysit their newborns, smile when they see me, and give me hugs before they leave. Of course I get eyerolls when I talk about fluorine and chlorine, but tbh, that's too much for a lot of people to handle right now. Someday people will understand, but right now most people don't know that Einstein had anything to say except for 'E=MC^2'. Hang in there my friend.
