Seeking the advice or help of concerned family members and friends could be of great help but sometimes they are limited because most of them lack the needed counselling skills.
Help from family members will be the best since family members are closest and also understands that estent of damage such attitude has brought upon such person. The only challenge is that, most people don't bring family to the cause of the damages they effect, they tend to hide it away from them knowing that family needs no approval to activate a corresponding correcting measure on them.
At least with help from family members, you can provide a little solution to solve the problem of gambling addiction. Family members can support gambling addicts to get out of their gambling zone and do other things. By doing this, gambling addicts can have substitute activities for gambling.
His family members can also accompany him while doing this new activity. It can relieve the boredom of gambling addicts because doing several new activities may not be able to divert their attention. But with the presence of his family members, he can be enthusiastic about carrying out this new activity.
And by doing it regularly, he can have a new habit. It can be a distraction so he doesn't think about gambling. If he is serious and stays focused on other things, it is only a matter of time before he can recover from his gambling addiction.
