Is there something wrong with me?

I have feelings inside of me that are very odd to others but seem fine to me.

If I were to die tomorrow, I would be happy knowing that I've had a great life. It hasn't all been good but all the lessons, and amazing things that have happened make me feel happy for who I've become today.

I'm only 20 and I wouldn't mind losing my life tomorrow if it means I get to go to heaven and be with the lord. Well mostly. However the only reason I don't want to yet is because I have family and I cannot leave them on earth. I'm not suicidal and would never take my life, but I wouldn't be too upset if something did happen to me. I would just be heartbroken for my family on earth.

Is this odd for me to feel this way at such a young age?
