I've been on a plane before with more money in jewelry than my life insurance policy, and it's one of the scariest feelings in the world... if you lose it, you have to pay for it yourself, and you don't even get to keep it!
I definitely understand not entirely fitting in. I think everyone has their own version of feeling out of place and I think one of the great things we have the ability to do is to know it's all right. It's OK to have that awkward phase.
