Of a truth, loneliness or being isolated all the time is bad because you will take some nasty decisions that might endanger your life without anyone noticing. So far as gambling is concerned, it is important you relate your gambling habits to someone you can trust because sometimes you can lose a bet and fall into depression without anyone noticing so at that material time it will really be dangerous to ones health because your thoughts will be filled with so many negativity but if someone knows about your gambling habits they can check up on you from time to time to know if you're fine or not.
That's why if someone feels lonely or isolated, as you said, they must find a way out before it worsens. The advice we can give is to look for people around him and start telling him about his problems and if he is really lonely, he can ask for help from people to invite him to do something so that his mind can be diverted. By doing something, he won't feel lonely and usually, if people feel lonely, it's because they don't have anything to do. He will feel that his life looks monotonous without any significant changes, so this must end immediately, and the solution is not to come to the casino and start gambling. But he must be able to do something that can keep him busy so that his mind can be distracted and he won't feel lonely. Some people prefer to join a charity where they can finally interact with people and do something useful there. And that will eliminate his loneliness because, from day to day, he will become busier and busier taking care of it, and it will not occur to him to gamble.
Indeed, loneliness may be difficult, and meaningful activities can help. Recognizing that everyone's journey is different is vital. As you said, joining a charity may be a lifeline for some; it gives them purpose and a sense of belonging. For others, the solution may be more complicated. Consider gambling. While typically perceived negatively, especially in the context of addiction, it can be a source of social contact and leisure if done responsibly. I've known people who enjoy occasional, limited gambling and community. Balance and self-awareness matter.
While avoiding casinos is a good idea, not all gamblers become addicted. Some use it to socialize and get a thrill. The objective is to promote healthy gambling and provide support for those who need it.
