Who Am I?

I feel like I've changed so much these past months. I just don't really feel the same, and when I look back, there are many differences between who I was and who I am now. I think it's because of all the time I've spent by myself, really learning how I behave when I'm not influenced by anyone else around me. It's kind of strange, realizing how much someone can change in such a short amount of time. My friends have definitely noticed. They tell me I don't sound as crazy and happy as I used to all the time. It's not normal for me, they say.
Have you ever wondered why or how people change? Why, if something terrible or enlightening should happen to them, that experience could change their whole disposition? I find the inner workings of the human mind to be fascinating, and I think I want to study psychology when I get to college. Maybe I can be a psychiatrist, even work in a hospital for the mentally ill. That would be my dream job, other than singing for a living.
I don't think I've ever mentioned that before, and if I have I apologize. I've always wanted to be a singer, ever since I first heard Bring Me To Life by Evanescence for the first time back when it came it out. 2003? About a decade ago. I was five years old, maybe six, and since then I've been practicing and practicing so that I could be half as good as Amy Lee is. Of course, we never had the money for professional lessons, so I've had to teach myself and get free tips from the Internet. I don't mind, though, because I have fun training every day. I never get tired of it, and people say I'm getting pretty good, so I figure I should keep up whatever it is I'm doing right. I'm going to be in the chorus at school this year, so that should be good practice, too. It's practically professional lessons, AND it takes up a whole period during school that could've been for something...ahem...'less interesting'.
I really enjoy writing these blogs, and I think during the school year I'm going to start writing one every day. It seems like a fun way to pass the time after school. After all, I don't have friends to hang out with all the time, so I need a good time consumer. I'm going to try to hold myself to this, because I have a tendency to forget to keep promises.
