My opinion is that if someone is being mentally abused the steps are:
1. Realize what is going on
2. Get out of the sitsuation and document with the police
3. Avoid being with the person being abusive
4. If abusive person continues to harass get a restraining order
The abusive person most likely is someone who enjoys wrecking someones mental state or thinks that they are in control by their actions.
It has been my observation that step 1 is the hardest one.
We will spend our old age surrounded by idiots following government rules.
