Before
With some diagnoses if you believe you don’t fit that diagnose anymore you can have it removed, this doesn’t work if you have anything you are still medicated for or anything that has caused you issues recently
Or anything severe
You can’t undiagnose yourself with schizophrenia but you can with depression and anxiety and even mild autism and adhd/add without needing approval of a psychologist
After
If you no longer think it is suitable for recovery, you can use it with any medication that will not work if you are treating it or if it has not caused any problems lately.
Or something heavy
You can’t cure schizophrenia, but you can also add depression and anxiety and even a little autism without a psychiatrist’s permission.
