Well glad you seem to be getting kitty help. The anxiety may still be there though. Enjoy the company you have. Take pictures of those cute, funny moments. We understand the cycle of life, and MANY MANY MANY years from now, when that time comes.... those pictures will help bring back all those great and funny memories you have had.
Nobody is promised tomorrow, so enjoy today to the extreme. Your obviously a great 'mother' to Griz. No doubt she will start turning around for the better.
