Sickness

What is it like to be sick? To never have a moment feel healthy? How harsh is it actually? Lately that question come a lot around my head. And I guest I can never answer.
I'm not what you call a healthy child. In fact I get sick a lot. But it only small one. Catch a few cold a year, sore throat is some kind of daily matter. But they have never been a trouble for me before and most likely would never be. I get use to it and it doesn't bother me at all.
But things are different with my friend. She have a trouble with her bone structure and have try to put up with it. Finally when she decide to deal with it, it have already got out of hand. I want to said something so much, want to make her feel better but I can't. I don't know how she feel, talking to her I was so afraid I would dig up the old wound. I want to tell her just cry but then what. I cry so many time over so many thing. It's never help. When I cry I don't feel better, I only relive that bad moment over and over again. Would it be the same for her? Would she live that moment again and again or would it help her release all the sadness and move on? I really don't know. I have trouble. I'm lost in my own world but all those trouble I could do something about it, fix it, make it better. What about her? She lost and she can't even help herself. I wonder what would I do if I'm in her place? When I have my arm broken I been through a little panic. It feel so scary, no it feel much worst knowing I would never be the same as I was. You can't believe what I did back then. I disobey the doctor's order and try to put my arm in use. Stop every time it hurt but continue shortly after that. I don't know if it help but I got my arm back. It feel as good as it use to be. Has I go against nature back then? Or it is just a normal thing? It work for me to try do what I feel need would it work for my friend?
So many question!!!
