This is BULLSHIT
People with Mental Issues often cant get better themselves, and they cank ask for help, so they send signals.
I will give you an example, a bit extreme. People with suicidal tendencies, often have silly attempts at the start, those attempts are called calls for help, because its their subconcious doing an attempt that will obviously fail, so that others take notice and help them seek help
But the people around the mental health person need to act, because if nothing happens, the attempts will get worse
Its VERY RARE, almost impossible for people with mental health issues to be able to solve them themselves
