I can not control my greed in gambling, because I want all at once and more. Because of this, first I lost a lot of money

You may not control your gambling activity that easily but you can if you are willing to not lose your money and your family. That is the nature of gambling, to make someone lose money and make them greedy and be worse at the time. If you want to stay in your family, you must be controlling, supressing your gambling desires.
