Gypsey sounds like a real blessing in your life and an amazing cat! It is ok to grieve the loss of someone very special. Gypsey will always be with you in spirit, and in your mind. The beautiful times you had together will always be there for you.
It might be nice to put together a celebration of Gypsey's life..write about some of your favorite stories, pictures, and maybe even share this with T or some close friends???
Be gentle with yourself.
