Do you ever want to disappear sometimes?

Just be gone for a few days, come back, and not have to worry about people asking where you were, explain what you were doing, having to catch up on work... Just to be at peace with yourself and try to figure out who you are? Be completely isolated from people you know, and have just yourself for company?

I really don't know who I am anymore. Am I the happy girl people tend to befriend, who loves meeting new people and sharing funny stories? What about the one who gets overly stressed when she can't solve a problem? Do I actually like chemistry and school, or are they there just so I can feel like I have a purpose? Do I love talking to people just because, or because I'm afraid of being alone? Do I help others because it makes me feel good about myself, or because it makes me feel like I might be worthwhile? Am I the sarcastic one, or the one who cries when an ill-timed, but well-intentioned joke gets flung her way? Or quite possibly, I'm just a mess, an amalgamation of conflicting feelings and emotions, with no order to the chaos.

I don't know, and I'd really like to find out, but it's not something I can do when I'm always concerned about tomorrow.
