My sister is in the hospital, we were swimming.
and she couldn't breathe, I think she got too much water in her mouthe, or something.
So me, and my mom drove her up to the hospital around 5 or 6.
Then the doctors said it might be a while, because she has asthma, which adds on to it. :/
and she has it really really bad, and now i am at home (just got home)
and I am worried to death! Could I please have her in my prayers, ):
thats all I am asking.
