I am so sorry to hear about your mother! My dad was sick this past fall with heart problems... so I know how scared you must be. Do your parents live with you, or do you just go over to their home and help care for them? It really does seem as if you've got so much going on, and you must be feeling as if life is spinning out of control.

I have no opinion on whether or not to "go for it" in regards to the kitten, only that if it is meant to be, she will be available once you are ready to bring her home. If she finds another home, then she wasn't meant for you. In the meantime, take care of yourself too! Please let us know what happens to your mom!
