I have several reasons to stop when gambling, 1). I don't feel like gambling anymore, 2) lost all my funds, 3)satisfied enough with the profit I got from gambling, 4) when I think luck isn't on my side(meaning ridiculous losing streak), 5) have something else to do. There are more, but I think it'll be pointless to list them all. Overall, I have a lot of reasons to stop gambling.
It's hard to find people that can really say that they are satisfied with the profit they make or they have made in the past. These are all reasons to stop gambling, did you get these feeling all of a sudden or are you just trying to be careful with your finances, there's nothing wrong with trying to play safe or avoiding drama totally. Although I don't understand how you lost all your funds and say you are still satisfied with that Profit you make
