I know this was sincere, well-meaning, thoughtfully stated, and appreciated. Having said that, I am not sure the right "life-balance" is enough. To presume so assumes, at least to some degree, one doesn't have a true issue going on. Take weight for example. Everyone knows you can take two people, same size, same lifestyle, same diet, and they can be dramatically different in weight. Why is that? I believe it's the same for those suffering from anxiety issues.
I recently learned a few years ago that my wife's family (both maternal and paternal) have had debilitating anxiety issues dating back as far as memory. Her older cousin took it upon himself to go on a sort of vision quest to find answers. He found a doctor. This doctor spent 6 months working on this guy's father. The result? At age 65 this dad finally had peace... totally. My wife's cousin told me that when this happened he had a 'dad' for the first time in his life. No more panic attacks, no more anxiety, no more selfishness (unintentional). He then went on to help other family members find the right 'mix' of meds to bring the brain in balance.
This doctor STRESSED that our brains fire and release chemicals at 'normal' rates in about 80% of people. The other 20% misfire and release the incorrect/wrong amount of chemicals and the end result is skewed. I tend to believe this is true. I really do.
When I first married my wife, I was always caring, respectful, and nurturing.. but on the inside, I was thinking, stop the drama.. be an adult.. suck it up. Even though I never once said those things, I now feel badly for having ever even thought them.
