What do you do if you feel sick and know one will help you?

I know how it feels to be unable to do so many things and no one will help you at all. I felt the same way when I had a soar leg when I was nine and so close to a perfect Christmas. I felt as if I couldn't do anything. Eventually I realized that I was only thinking of the negative side of things. I should have been telling myself that at least I could still have fun, just in a new way than before. What I'm trying to say is that you should always look on the positive side.
