Please hang in there. You have worth and meaning. We are here only once as for as we know, and the odds against any one of our being born are great. Each one of us won a lottery by being born.

I think there may be pet mourning support groups. Please talk to someone if you feel too depressed. It is small comfort, to realise you spent more time with Bucky than most people spend with generations of cats. 22 years is a large part of your life. Just remember, your life means more than you know.
