I've read that crying can be good for people. But when we're bipolar and cry, people get worried. I couldn't cry for years, but finally after years of therapy, I can. That said, it's about specific events. I even got tuned up when reading a science-fiction book when a popular planet got destroyed. I thought that was kind of weird. I still have never cried after the death of my parents, but I cried recently when my brother-in-law died.
