If you continue following such kind of act when you are experiencing losing streaks, chances that you'll see yourself losing a lot and like what you mentioned, it can lead into addiction and we must stop that kind of emotion. Either force yourself or find ways to use alternative venue to put yourself to other things instead of pushing yourself forward and keep losing more. That will allow us to find that discipline we need to avoid making huge mistake and lose lots of money.
If losing streaks often occur in betting, then I would think about leaving gambling altogether. Betting is different in that the player chooses the bet himself, if he is not good enough in betting, and this often leads to losing streaks, then why do it, for me it means lost money and disappointment from lost money, it has nothing to do with pleasure and entertainment. The best way to avoid emotional disorders is to find yourself another hobby.
Its common sense but people are way too forceful on things on which they do believe that they can be able to take back those loses specially they are involved on gambling or betting on which its a common approach. There are really just that those times that we've been that too optimistic about into the actions that we are taking and hoping that something that could give out that positive outcome. Emotional control could really be gained through on actual experience from those engagement. If you arent that good when it comes to emotional control then you are really that bound into facing up tons of loses on which it will really be that resulting into much more disaster. Its not bad to gamble as long you do able to make yourself that having be that confident or having that discipline when it comes to money management. You are the ones will really be taking up such action so that it will be that not will be giving out such negative impact.
