You will always have us, enig. And don't forget--a person can feel lonely in a room full of in-laws. (Welcome to my life... )
Dear Abby says to find one or more people who will spend the holidays alone and get together with them for punch and cookies or a movie and dinner or a walk around the block. Better, visit a nursing home or a hospital or an animal shelter and even become a volunteer there. If you can give a little from your heart, you will get back tenfold. You need to be needed; volunteering will do that for you. Sit and chat with an old person about who they used to be in the world they used to live in, play Checkers with a hospitalized teenager, brush a few homeless cats.
