Is mental illness curable

Can mental illness be curable? I would say yes. I believe in the environment being the main role in how a person is. All persons have eccentric or idiOSyncratic things about them, but not everyone is labeled. I do think that "all roads lead to Rome." Just because there are or were problems in one's life, each moment brings you forward to the future. I believe each person has more potential than what you see. I don't like labeling persons with such and such an illness.
