I just got divorced last Friday and I relate to you on so many levels. I can't usually sleep at night, and that's when it's loneliest. He was also my best friend - before we started dating and our subsequent marriage - but I lost him. I'm still in love with him, but he says he's in love with someone else and doesn't think we can be friends again until I'm "not in love with [him] anymore". Since he'd been my main support, it makes life lonelier than I thought anyone could believe. It is a comfy feeling to just cuddle with someone, to hear them breathing next to you, to feel their warmth. I don't know if I've been much help, but I do completely understand. It's a lonely place in this world.
