you add greater losses, and you want to stop but you will definitely return because you still think you can profit from gambling..
I though being a martyr only applies when you are in love but I'm surprise when it could be also applies in gambling. It is just like what you have said, we know that we are just repeating the situation(losing in gambling) but still we chose to try and try it again, hoping to get some profits, sadly it turns out to be the exact opposite thing---we lost over and over again, and we tried it again.
It is like a routine for us, that is why it is hard to ignore it for even a day or a couple of days because it is already became part of us, and that is a bad thing.
