Forgive me if I'm stepping in where I shouldn't, but I totally get you. This is the same thing my sister and I experienced, which why we left for a whole year. It's good that you realize this though and that you're aware of it, and it's good that you feel the need to act on it.
I've heard that it takes 40 days to break or make a habit, so once this happens, it will probably be a lot easier to set a pace for yourself if you every consider returning, like to visit once a week, once a month (like I'm doing), or even once a year. Self control can be hard, but if you pray for God's strength, it is possible. He will help you.
Again, please tell me if I'm stepping in where I shouldn't, but I was just offering you advice on my part, because I totally understand where you're at. I don't really know you that much, but from what I can tell, a lot of people love you on here. I know for one that they will always respect your opinion and whatever you decide to do.
