What is you ideal outcome to this situation and how can you make it happen ...so for me I want you to be less sad for starters. It sounds crazy but I learned this in CBT if you sit in a room and just try to laugh for ten minutes you actually feel better at the end. Its just a short term intervention and won't solve your problems but its funny how odd the idea of laughing to yourself in a room is and often that's enough to laugh about. Did you ever read that hyperbole and a half about depression and the corn?

Hyperbole and a Half: Depression Part Two

For me that's how sadness is---there is when you are terribly sad a point at which you can't take it anymore and something will happen to switch over to an almost uncontrollable laughter and you start the slow climb up to feeling better. If you can't laugh its possible that smiling is enough---there were studies where people had to hold a pencil in their teeth for some amount of time you know cross wise so you're almost smiling and they experienced a positive change in attitude. So maybe start with a smile if you can't manage a laugh?
