I don't think that this is a good idea to play gambling to escape worry, trouble, boredom and another else because we cannot enjoy the games and we can get lost too much without we realize. it is good for us if we play gambling without negative things in our mind so we can enjoy the games and have fun with the others. maybe if we feel to worry, trouble, boredom and else, we need to have another activity to solve the negative things in our mind, for example, maybe yoga will be the best things that we can do.
From my on perspective, I truly agree with you. Gambling has never really ended up having a good ending story except for those who are just extra lucky anyway and do not end up gambling back all their winnings. There are other better places to escape worries, boredom, loneliness and the rest, but gambling is totally out of it.
And the worst one the OP mentioned was grief or lose, when eventually you are going to be losing more with gambling and with huge grief over your loss. Not a good call at all.
