Well that's true, I mean I also quite agree with what you said that not all problem gamblers want or dare to ask for help from others, especially those around them, I have a personal reason for this that it is most likely difficult to ask for help, namely because remembering gambling is an activity that tends to have a bad stigma in the eyes of society which may be one of the reasons why they prefer to hide their problems even though they experience a lot of pressure, especially from financial problems that are destroyed by excessive gambling.
Maybe they also think that by telling the following and asking for help from others, it will only cause new problems such as dealing with the police, especially when they are in a country that prohibits gambling, so this is a bit confusing, especially when you are in a country that prohibits gambling because of course there will be a fear in you to ask for help from others because of the fear that the action will actually cause problems, but I think asking for help from people close to you like friends for example, maybe that can still be done.
Sharing an information about your gambling addiction to someone could actually destroy you also which is why some of us are not open to doing it. Maybe they wanted to deal with it privately
on their own and I take it their direct relatives doesn't know it too. Because if they do, the adult in the room will come to visit them and tell them like they are a little kid. They wanted to avoid this kind of confrontation because it will lead to more confrontation.
Of course that is another effect that can arise when you try to tell others that you are involved in gambling, at first your goal may be to ask for help from them but we never know how in the end there is also the possibility for them to do something that actually causes problems for you such as reporting it to the police or telling your parents, that will always be a possibility that could happen. On the other hand this is also one of the problems that causes delays related to the development of recovery for a gambler who is suffering from addiction, so maybe they can only wait for time by trying to fix everything themselves in the sense of changing their approach and reducing their gambling activities in various ways even though they basically really want to do it.
