Medications make it possible for the formation of new pathways of thought. They impart, and enable, structural changes in the brain's chemistry. New pathways can lead to new thought processes and belief systems in new realms of the mind. It becomes possible to transform your mind and find soundness that wasn't there before.
The healing of a schizo-affective mind depends, in large part, on the person seeking healing. A medication that makes a positive impact on brain chemistry, one you're at peace using, is the chance to develop new thinking.
God will aid a soul that seeks to heal the mind. He'll use the most unsuspected circumstances to bring about events to bring the right medications to the mind in need of them. But medications alone are not enough. Effort must be made to take possession of one's mind. You can learn to change your thinking. You can feel it. It's as if a hand is grabbing the mind and taking full hold of it.
Change and healing can be long, slow processes. They can take many years. They are greatly aided by the person seeking to heal their mind. Moving in the direction of a fully functioning life, the one they envision, can lead to all the joy and happiness of pursuing what you truly want. Medication may still be needed, but you can support yourself without SSI. Ideally, you'll find what you want your life to be. If you're willing to pursue it. Risk the loss of your old mentally ill life, and create a new, mentally sound one.
