I lost my dad on 31st December, 2010. He had a cancer in his rectum, which eventually reached his lungs. My mom and I are still trying to recover from our loss :-(
I know this goes against the ethos of HN, but life is really not about software. It's about people. Get out there and live life and meet people. A lot of exercise and playing loud angry music was also really good for me for a while.
