Online gambling gives the privacy than any other form of gambling. This happens everywhere and I too have done it. Not as a saint, but I used to give advice to stay within the limits. The funny part, the same day my loss will be higher than the one I give advice. As they don't know I was into gambling they take it good. If they know about my gambling activity, surely they'll have a negative thought on me.
I think you are in a very difficult society. where gambling is not legal and common in society.
but now there are many online casinos. and it helps you in channeling your passion for gambling without having to affect your social status. you will stay safe.
but in the real world, of course, you have friends to share experiences with or just tell about your online gambling. I'm sure you have because I've also experienced what you are going through.
