Why did I ever WANT to grow up?

I am completley aware of how insane this sounds however, I feel that I must get it off my chest. Today is my birthday, HAPPY BIRTHDAY TO ME. I should be pretty excited except that I'm not. I turn 24 today and although I know that in the long run 24 is still fairly young I just can't help feeling OLD! I understand that I am being ridiculous and am perfectly aware of how crazy this is. I just can't help the feeling. At 23 I still felt as if I had every right to make poor decisions and act crazy and wild and not worry about anything because I have the excuse "I am ONLY 23" Now I feel that I no longer have an excuse to not act like an adult. Twenty-four seems like an official adult age. Although overall I must admit I am not quite like other 23 year olds I still am fighting my way against adulthood... Why did I ever want to be an adult when I was younger. I should of listened when mom said "stop trying to grow up so fast"!!! I should have taken extra years in college instead of doubling up on classes to graduate on time. I should have gone straight to grad school, not bought a house, or a car, and live the life that most immature/irresponsible 23 year olds live...But now its to late I am 24 and officially an adult. This makes me a little sad! Goodbye my youth! I know I am totally being dramatic but thats me so appreciate it!
