1) Gambling brings you loneliness, or makes you feel alone or want to be alone, it can isolate you from society or from other important events in your life.
This isn't just for gambling but it's for everything that you do alone. You are isolating yourself from the society because you feel uncomfortable dealing with other people.
2) It can suck your energy or your happiness, it can get inside your head and won't leave you alone until you gamble again.
A fact.
Whenever we lose, this starts to get into our minds and we can't be contented of just thinking on how we're going to recover it. What we want is to recover it with our bare hands and that pushes us to gamble more.
3) Not to mention it can can destroy you financially, you can lose a lot of money in a matter of seconds/minutes/hours/days. Some stories show how people lost over millions of dollars in a matter of hours or days.
4) Gambling can also destroy you individually, not only financially, you can lose your family, your job, your friends or relatives.
These 2 reasons are on point.
I've watched different stories on how they made themselves broke for getting that much addiction in gambling. They even lost not just properties, went bankrupt and even lost their loved ones.
While reading all your points, I can feel the pain damn.
