1. You shouldn't spend much money because it will harm the family. (Limit your funds)
The money management is important to limit the possible harm, there is no limitless bankroll to test every new strategy with real funds. Better to test the strategy in demo first.
2. You must have good self-control, it is one of the keys to be successful in gambling.\
Emotional control is the part of mastering yourself and ego death is the peak point to reach.
3. You mustn't get loans, you will be trapped in debt at the end.
The worst part of the Gambler's Fallacy, the interest plus the main debt grows each day. The family help and therapies are necessary for healing yourself.
4. After you can win in a gambling game, you are better to stop (break for a while). Don't be greedy to push your luck!
5. Don't expect much to win in gambling, most of them are luck-based. Think rationally!
I advise taking a break after the every dip and thinking about the made mistakes in the game session. Exploring the game session with calm mind will help to control yourself and limit your loss.
