My friend, I am the mother of a severely disabled adult child. There is no greater honor for than having to care for him. Sure, I have days when i wish I could drive away and not worry about him for a bit, but he brings me joy and wisdom that I would not otherwise ever have had. If your parents love you - and from what I read of you who could they not? - caring for you is a burden worth carrying. You bring blessings to them every day. I hope it goes well for you today.
