Being a father at a later age is different from when I had my other two daughters when I was in my 20s and 30s. If you're in your 60s and you're with the kid every day you're dealing with the mind of a child so it opens up that childishness in you again.
I start to think there really is no cure for depression that happiness is an ongoing battle and I wonder if it isn't one I'll have to fight for as long as I live. I wonder if it's worth it.
