I know it hurts terribly, and I'm so sorry that you have to go through this. Just focus on getting through each day at a time, and it will eventually start to get easier to cope with. It will probably be really hard at first, but try to keep yourself busy... whether it's work, or a hobby, or spending time with friends. Try to preoccupy your mind with things you enjoy, I know it isn't easy, but it may make things easier to handle. Hang in there, things will get better.
