This topic will stay open as long as there are many members here sharing their same stories and suggestions. Gambling is a fun activity, however, it should be taken with much cautious. The best thing to heal from addiction is the first step which is admitting to yourself first and sharing with community, family or friends to seek help.
I did similar things several times, but the amounts were small, because I realized that it is like a funnel that can suck us in completely, the only question is to stop, the decision about which no one except ourselves will comment. I have not played for high stakes for a long time and have set for myself an amount above which I simply close the game and that's it. This helps me to stay in good shape to this day.
