A lot of people tend to hide their psychological issues from others because they hesitate to discuss things with others, even if they have people that are very close to them, they still sometimes don't share what they feel, and that becomes the reason why many people commit suicide only because they've been suffering from a psychological issue that they never discussed with anyone nor did they seek any help but they just kept it to themselves and it kept eating them from the inside.
It's definitely the responsibility of those who are close to them, especially the parents for their children from an early stage, they should take care of every single thing so that the children don't get into psychological illnesses that will eat them up from the inside and they won't be able to live their life and will finish it some day in the future.
Because there's still a stigma running around the world, people still not accept or understand mental health issues which addiction could be one. It should be taken action asap before anything happens in not a good way because it can ruin themselves and the people around them, only professionals can help them.
Taking action can only be possible if someone discloses the issue with someone and tell them what they are going through because it is very difficult to identify an issue that is within someone and not visible physically, sometimes, the parents of a person can identify that something is wrong because people with such issues tend to have changed behavior and those close to them might be able to understand that something is wrong.
But when asked, they might hide their feelings and not let everyone know what's happening which shouldn't be the case, a mental illness is more dangerous than a physical illness because it will make you do things that one should never do.
