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.
Each person do have its own experiences and having nightmares on some cases.So far i havent experience on losing too much with gambling yet i do know on what are the things would be mainly affected if i do able to spend out the money which are intended for my family needs and wants in life. Only spent a little for the sake of entertainment and never go beyond or cross that line.Well, we know on whats the reality in talks of this matter where there are really people who wrecked up their lives because of playing too much gambling where they didnt able to realize or think earlier on what would be the consequences that lies ahead.
