How long has it been since you asked for help – hired or volunteer – so that you can be your own person for just a bit of time? Too, long, I suspect. This is a new year, which makes it a good time psychologically for an attitude adjustment on your part. Changing your attitude toward your caregiving responsibilities doesn't mean that you don't love the person you are caring for as much as ever. Changing your attitude may even be evidence, once you think about it, of the depth of your love.
