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.
A lot has changed over the past years and I think that a lot more people talk openly about mental health issues than they did in the past. But mental health issues isn't always the same. I think talking about mental health when you lost a loved one is different from talking about an alcohol or gambling addfiction. Stigmatization isn't specifically happening for mental health issues in general, but for some types of that illness. That still makes it difficult for people to open up.
