I’m not sure if you are saying you need to stop gambling or not. Don’t get me wrong, I think you need to stop but I am not sure you believe it.
You imply that your gambling is a symptom on a wider, personality problem. That may be true, but gambling isn’t going to help you to deal with that. Neither is leading a closed life. You do need to open up, to a group or trusted individual, preferably face to face. Someone local, who knows what help is available in your area would be good.
Come back when you can hopefully clearer and maybe get more targeted help.
