When I fell stressed about gambling whether not for making a good profit or for losing on match or for losing a good amount I try to watch a movie or dram and I feel better after watching movies as well as dramas. Also, I stay away from gambling for a good number of times so that it can't affect anything on my health. If I do not do this then I can't concentrate on any of my tasks whether offline or online.
Actually it is quite simple if you want to know how to avoid stress when gambling, namely stop gambling (that's all but most find it difficult to admit because they always want to involve gambling in it).
What you do by watching a movie is one of the most effective diversion ideas, especially for those who like action movies or adventures with a season that can reach 20 episodes. That is very suitable because you will be busy with a long duration until you don't have free time to gamble. Because based on experience, the thing that can best help you get out of the stress of gambling is to have other activities outside of gambling.
