Too much of everything is bad, and good that you are able to put yourself uncheck, btw what about your friend do you also check to see how far the same negative effect of too much gambling have affected him?

Try and check on him to know his current state and to see if he be needing your help as well, because if your friend is already addicted to gambling and hasn't make up their mind to quite, they still will pause a great risk to you keeping them around.
