I thought of the following rules:
Therapists shall be relied on for diagnosing abuses on victims and leading to a penalty on the abuser.
For instance, if someone constantly belittles another, the former would get a penalty of paying a periodic amount of money for treatment time, for instance. If the person has no credit account, authorities will use one of the person's parent's credit accounts.
Further with that, if one causes physical violence towards someone, they will get imprisoned and perhaps hospitalized.
To support the latter idea, various articles over the net point out that most of the time, the people who are diagnosed with mental illness suffer abuse, rather than causing it.

I will add a key sentence - "It's not being different which is the problem. It's how people treat the different which is the problem". However the mental health system doesn't see it that way - if someone is abused, they're the one usually treated and not the abusers.
