Aww, I'm so sorry... I have asthma myself, but it's allergy induced and not very serious. It's got to be really difficult, not being able to see your dad, too. And maybe you and your sister could try to understand each other more? I understand she's probably annoying--I personally find my brothers annoying--but she's probably not doing so hot, either. As is the point of this post, it's much easier if we can at least try to understand each other, and try to be here to support each other, especially our own families. I'm happy I was able to help you during this time, and I hope things get better for us all soon.
