some people react to insecurity by just trying to shut off emotions. there's always a big conflict between wanting to feel something and wanting to protect yourself from further hurt by shutting it off before it gets to that point.
i think losing a parent in any way at a young age creates a big gulf between a person and other people who have not lost parents. for one thing, it is very hard for me to relate to 40-year-old ppl who are just now figuring out that their moms or dads might be getting old or dying and are freaking out about that. i just want to laugh at them.
