Gosh you really do have a lot on your plate to deal with, I can well understand how much you want this adorable kitten, been there myself, for me it was a financial decision, I just simply cannot afford another cat, no matter how much I would dearly love one.

Maybe it would be best to wait a while and see how things go with your mother, if she is meant to be your's she will be, it is so hard when your heart strings are being tugged so hard, I know the feeling.

I am sorry your parents are ill, and I hope your mother will improve, you are young and it is a lot to cope with, my thoughts are with you and I hope you get your kitten in the near future.

Positive vibes being sent your way . TAKE CARE!!!
