I know this isn't what you want to hear, but being alone just plain sucks! I too am there with loss of appetite (eating is a four letter word for me) and increased smoking at times. While we are supposed to do things for ourselves, it's much more enjoyable doing them for or with someone else! Let's face it, people do need people (didn't Barbara Striesand have a song like that?). There are times when we want to be alone, which is fine. But for the most part it's a pain and hurts! About all I can say is some days are easier than others.
