Well you need to get some discipline from somewhere my friend. There is "never any reason to lose "all of your btc" gambling, even less is there any reason to cry after the fact that your actions sucked and could not be controlled. If you can't stop gambling all of your btc it is time to seek help for addiction.
It is easy to walk away without losing all of your funds if you're not addicted.
It is risky and that is what makes it fun.
That is why you can't do anything` because you have told yourself you can't do anything.
You can do anything you want and that includes being able to stop gambling and crying as a result.
There is help out there for you should you choose to accept it.
I could not begin to help you on a forum thread post but I have dealt with it myself and it can be beat.
Pm if you want to sort it out.
