How long is your term of enlistment and how old will you be when you are discharged? I am unfamiliar with the terms of enlistment for the guard. I find it interesting you acknowledge your inability to find balance in your life and have decided to pursue a path (military) where your freedom and actions will be curtailed or controlled by others. I would find that situation exhausting and probably stressful.
If you have too much free time and need to fill it, why not volunteer someplace?
