I know that others may disagree with me but I believe that your mental health and happiness is half the battle. I dealt with depression issues and other things when I was younger and going to CF camp (when it was still around) helped me a lot by letting me meet others. This forum can do that as well but it isn't the same. I am a people person and know that people that I care about mean everything to me. I know that just going outside my front door, I can catch half a dozen bugs and things. I go to school and I know that other CFers don't wear shirts or have tatoos that say 'I have CF stay away from me' so I take a risk everyday going to the grocery store, school, the library, anywhere there is people. My CF friends made me feel better mentally and even when they had MRSA and Cepacia I didn't catch it. I was so much healthier. They all passed away when I was in high school and that was very hard for me but I feel better to have known them and spent time with them. I caught cepatia many years later while in college I might add. People tried to keep me from my grandfather when he was dying because they didn't want me to catch anything but it meant more to me to be there with him and spend that time with him than anything else. I used caution and washed and wore masks and everything on these occasions that I was around them all but it meant more to me to be around them than not. My outlook on life is simple - it is short and our hand has been dealt but its up to you how you play it. I find my happiness from the people I love and I would rather have a shorter life surrounded by those people than a longer one without them. I think because I took as much care of my mental and emotional health, that is partly why I am still here today. Just my 2 cents and as I said others may disagree but that is how I feel. My response is to talk with the teacher, see how she feels and if the feeling is mutual, talk about precautions BOTH your daughter and the teacher can take to keep each other healthy and stay in each other's lives.
