There are many factors that can effect you outside of the gym, which in turn can effect your presence in the gym. One thing I realized a long time ago, is that if you can find a 1-2 hour HEALTHY escape from all of your problems, keep it that way. It doesn't have to be the gym (snowboarding, reading, music etc.), but in this case, we will use the gym.When you're in the gym, your focus should be on just that: Training. During your time you cant fix anything going on outside of the gym.
