Sound to me like you have come to some GOOD foundational awareness. You are correct....if they aren't willing to do the care they need to do for themselves why go out of your way to care for the worsening symptoms they are causing to themselves?
Ok....from personal experience.....you do know that time spent with our horses is a much better antidepressant than chemical meds any day. They give real LOVE back & they even listen better than most people. Time with your horses is much more well spent IMHO.
