Re: Please help. Sister is sick. I have to take care of her.
I know it is hard to deal with. I have two children I have to take care of when they are sick, and I have been scared of this since I was much younger than you. A long time to cope.
Best advice I can give you is to breathe, and to change your thinking. Watch a movie (I have specific "Panic Attack" movies), play a game that keeps your mind working.
Also, though I don't know where you are from, the sv* seems to have hit very early this year here in Alberta. The good news is, is that once you get it, chances are you won't get it again. Most ppl don't even get it every year. So, try to keep that in mind.
The bloating is partly imagination and partly eating and partly panic. Peppermint tea helps. Stay strong!
That, which does not kill us, makes us stronger!
