Just pondering this.
The majority of articles on the subject relate to domestic abuse. This also means there is a particular group of people who promote this and a particular group of people most at risk of this type of abuse.
There is also a particular type of person who is more likely to inflict this type of abuse and restrict others from knowing this is abuse.
How can you tell when someone says they are suicidal that it is a cry for help or attention seeking? How can you tell when someone is at risk and when someone is being manipulated?
How can you tell when someone is in need of support or is being controlling?
When do you believe and when do you treat with a degree of skepticism for your own protection?
I think this is something that needs a little attention in its own right.
Is there a particular pattern or signs or clue to how to tell the difference?
