That the least that I can wish for

Mental illness is a long term treatment...it is treatable but can't cure completely. Do we have any hope that one day we can be cure? I have been reading some articles on the internet....and they stated that they also don't know how mental illness come from? For me I think the only way is ask for prayer healing and continue to chant for miracles to happen. But if no miracle happen, I only hope that less strange behaviour and anxiety coming on me. That the least that I can wish for.
