Teenagers too often have to deal with loss and death. You had to cope with the untimely death of your brother; how can young people deal with such tragedies?
The most important role models should and could be parents and teachers. But that said, once you're a teenager you've probably gotten as much of an example from your parents as you're going to.
When you have a tough loss, go through it and agonize. I had one loss that I still want to change, but at the same time I realize it is an important part of who I am.
Unfortunately, there are so many people who live their whole life in a place that is safe and protected and simple and they don't really have that strength inside to fly.
