Social distancing should not lead to social isolation, so talk to your friends and peers and discuss your gambling problem with them. Having support can make a big difference.
It will work but sometimes, once a gambler is now slowly turning their activity into addiction, they won't notify anyone about it. The friends or closest ones need to take the action first on that case.
That can happen if their friends or closest one know about his addiction and he can approach him and tell him that he needs to solve his addiction. If it is not, that gambler will not solve his addiction and go deep into the gambling games without a chance to solve the addiction problem. That needs courage from the gambler to tell about his addiction to help him solve it.
