I also suffer from that kind of situation but I was to brave to tell my family about it, of course, you must accept their anger because you deserve it, but it causes me sleeplessness nights because we need money very bad back then, but it made me realize that gambling is something you must have control and don't pour everything even though it is tempting to do so.
Lucky for you, you already told your family about that. Until now everytime I remembered how much I'd loss in my gambling addiction 2yrs ago it keeps me awake till morning, it is still a nightmare for me, since then I learned my lesson not to put all my assets in a game, because I lost everything on that game.
There were times when I also lost sleep due to loosing in gambling as I was one of the uncontrolled gamblers and I didn't knew when to stop gambling even while loosing huge amount of games in a row and I was one of those who thought that they would cut back their losses after loosing the games.
But now I have had help from many psychologists and therapists and now I am able to control my emotions and have limited the amount of money I gamble, now I just gamble for the sake of fun.
