Being An Adult

What does it mean to be an adult? Is it linked to maturity, age or a set of other factors that must be met?
I don’t presently consider myself an adult. I live with my parents, I don’t presently have a job and am reluctant to do a lot of things by myself. Why is that? I wish I knew, but I don’t know. I want to be able to do things by myself, but I have just always feared doing anything around a lot of people when I am alone. Could I be worried that I would be jelous, or perhaps afraid of being the odd one out because everyone else would be with someone? I am scheduled to get my hair cut next weekend, this is something I have always had my mother to schedule and I always go with her when I get it done. Shouldnt I at this point, being a person capable of driving, be able to go there by myself and take care of it? I can manage to get to the drugstore to pick up things I need occasionally, but I can’t go to see a person I am familiar with without feeling the need to have someone with me. I do fine on UNCC’s campus, I suppose because I am an individual amoung a lot of other inviduals, there is no collectiveness here. There are a few groups of people, but mostly individuals.
On another aspect of adulthood, I am a very responsible person and meet all qualifications of an adult there. I don’t act abnormally disrespective to people, I don’t do things just to do them (a flaw in my personality) and I conduct myself as I feel an adult should. I observe the wild and unmanaged behaviours I see on campus and I can’t believe that the parents of some of these people let them out of their sight without a leash of some sort. I could not live a life of being so non-caring of what I am doing or what others may think of me. Does this make me adult-like or just paranoid?
I do not know the answer to any of these questions, all I know is that I am not ready to grow up yet.
