I agree Charleygirl about mind over matter. I think there is an element of being happy with your lot and making relevant changes. The world is not like Noah's ark , 2x2 . Lots of people are alone one way or another and maybe it's about finding those things that make you happy, even alone. There was a thread about the simple things and I think that's important .
Maybe if you can fill some parts of your life with things that make you happy it can help in the parts that make you unhappy . I don't know , there are others here who have more worries than me , maybe they have good coping methods?
