One word: ALONE.
Let me explain a little bit...my mother in law just called to tell me my cat, which she has been taking care of ever since my husband died last summer, is really sick with a lung infection and the vet says she will not live through the weekend. Now I really do feel alone: a little over a year ago, I had a little family made up of me, my husband, and our adorable little cat Kitty Minky. Now I'm the only one left out of that family, and I feel so alone. I never saw any of this coming. And I am not literally alone--I've been staying with my parents--but even surrounded by people, I still feel completely alone...
