OP if poker is stressing you then you might have a problem. I don't know you or your lifestyle to come to that conclusion. I speak from experience.
When I first stared playing, poker was fun.
It was fun because it didn't have a control over my life. I played when I wanted to and was always happy playing. I found some success early and let it get to my head.
Poker became stressful for me when I turned it into a job. All of a sudden, I'm not spending time with friends or family, missing important events, not eating well, not exercising or doing any of the other things that made me HAPPY!! Poker had a complete grip over my life.
If any of this sounds familiar, then you need to step away from the game. How long? I can't say, that's up to you. I do guarantee one thing though. When you decide to come back, it won't be stressful.
Cheers!
