I know this feeling. It's an all consuming feeling of emptiness and loneliness. Even when you have people that care about you. You still feel alone and empty. And you want to just cry out for help but the emptiness consumes you. So true.
I do this all the time. With my husband, our children, a close relative, a friend. Sometimes I just randomly get an incredible overwhelming feeling and am reminded of his much I love them and how blessed I am to have them in my life!
