Do mental disorders fully resolve? Or do they become dormant?

Yes, mental disorders have been known to come resolved in various ways for different people. It works differently for everyone because I know someone who has told me they've been suffering depression for over 30 years. It has gone absolutely nowhere. That's indifferent to a few others I know. I know some people who have had eating disorders, schizophrenia, depression and many more in the past who have now overcome them instantly. So, it is dependent on the person. This is what a lot of people miss; the key to overcoming mental disorders would be figuring out that main cause for mental disorders before trying to heal them.
