I have wished many times that we can be normal again. I would love to play poker with my buddies. I would love to bet a few buck on a game. I would love to visit a casino again. However, I recognize that those are the thoughts of this addiction trying to feed itself.
If we look at it in a different way, can an alcoholic take the occasionally drink with their friends? I highly doubt it, even through they would love to. How about taking it another step further. Do you think that a drug addict can take some recreational drugs once in awhile? Goodness No! But the thing is, our brains are hardwired the same way. It is the connection to dopamine that causes our addition. Even though gambling seems much less harmless compared to drugs, the cycle of withdrawal and the cravings are the same.
Take this setback as a lesson to help improve your recovery. Self-exclude again and hopefully when that exclusion period approaches, take precautions and prepare for it. I remember when my self-exclusion lapsed, I reactivated my account just so that I could exclude again.
