I feel for you. I take care of an elderly Disabled couple in their home. They are like my parents. It's very challenging over the last few years I found myself going to food including lots of coffee with cream and sugar to get by. I've gained about 40 pounds over the last five years while doing this job. What I'm starting to realize is that you absolutely have to take care of yourself. No matter what it takes and no matter what that means to you, just do it!
