Being a chronic gambler is a very bad problem, unless you are winning, so I do not feel I should show people how much I lose.
This might also start to lead to other problems if other people didnt know of your problem and now they did.
I disagree. A well-written story about a chronic gambler can save lives of thousands people. Your name can be changed, as well as some other details that could lead to revealing your true identity, but it doesn't really matter in regards to the quality of the story. No one needs to know your real name, or the name of the street you live on. What people need is a convincing story telling them that while gambling they shouldn't go over certain limits, timewise and moneywise. And when I say "convincing" I really mean it. Such bullshit as "the house always wins", "it will ruin your life", "stay away from it" ... is not convincing, and never works.
If I had a story of evolution from a chronic gambler to a cured one under my belt, I would definitely allow to publish it, but on the one condition. It shouldn't be dull, full of stereotypes or boring to read. It should be like Fight Club, but about gambling addiction. We don't need another stupid book regarding this issue.
