Having home cared both parents before nursing homes became a must, and now caring for my 96 y.o. uncle who lives alone (healthy as a horse) as well as visiting his wife in a nursing home 3x a week, I can't tell you how satisfying, alas, difficult, it can be to care for the sick and elderly. I greatly admire the CNA's who administer to them. You have to be a certain kind of person, and I know that special person is you. I'm praying you get the job. The world needs more people like you.
