I’ve talked about stress and will continue to mention it often. The most important thing you can do while taking care of another is to take care of yourself first. It is definitely not selfish. Remember the instructions about oxygen masks on an airplane? If you are traveling with a child or someone that needs assistance put yours on first, then help the other person. Simply put, you need to be whole and rested so as to give to others. If you collapse, you are not much help to anyone.
The most important person in the equation will be you. If you are unsettled, so will those around you be unsettled. You are the one that will need as much care as your parent and you are the only one who can give that to yourself. That doesn’t mean you shouldn’t ask for others to help. That is part of what and how you give to yourself. It all begins and ends within you.
