The only thing that I can think of is by just go out and looking for a other hobby that is going to help you for sure if you manage to find the right one for you.
If that does not help then you will have to get some help from a professional.
I guess that is the primary concern that OP is facing right now. It is very easy to say that you have to go out and find another hobby but the problem there is how he is going do to it because in reality it really isn't that easy.
His facing some problem with gambling as the OP said but if he wants really to quit gambling for good then he shouldn't in gambling anymore find some hobby that he can do or repair their house plant some vegetable at your back of the house then chilx.
But the thing there is how possible it is. Especially if OP is being hook up by gambling too much as advice i think if the problem is really fatal OP should take first a good advice from the professionals
