I guess the one thing I forgot to mention is don't make the mistake thinking that "nobody knows how I am feeling." It's true, nobody knows exactly what you are going through, but many of us have walked in those shoes before. Use the resources around you to your advantage. Like Capo said, use the things that you enjoy as a refuge for the short term. But if you see a movie or hear a song that is a sad reminder, don't wallow - turn it off!
