The only thing anyone has to worry about 'catching' is a bad attitude - like that of the lady who was so cruel to you and our precious little Aysam. I'm so sorry that you have had to deal with such ignorance - some people take good health for granted - I think that is what allows them to judge other people.
I hope we can help rebuild your confidence and hope here. Like Andy said - we need to concentrate on the good things available to us - and the good people who are willing to help us:)
Take care,
Love,
Sharmin
