One more year to go

As senior year approaches, the reality of having to apply for colleges is starting to set in. I absolutely abhor this. Someone might as well be holding a sign that says "Welcome to the World of Stressmania". Especially since I'm not sure which college I want to go to and also what I want to major in. Teenage life crisis. Ever since I was 7 years old, I've wanted to be a doctor. A pulmonologist to be exact. But now I'm just not sure anymore, I'm feeling kind of lost. Cue the depressing orchestra music.

I have come to a few conclusions that might aid in my decision making though.

1. My legs turn to jelly when it comes to seeing other peoples' blood. That could be a problem if I decided to pursue medicine.
2. I hate calculus. 
3. I love little kids. Particularly preschoolers and kindergartners. They're so cute. They help make my stresses go away with their innocent and random questions. 
4. I would like to go to grad school.
5. I kind of want to be an elementary school teacher.

I realize that 4 and 5 contradict eachother, teachers probably don't need to go to grad school. Do you see my crisis now? I'm a firm believer in doing and going for whatever makes me happy. I don't want to end up spending twenty or thirty years inside an ashy gray cubicle. A good portion of this summer will need to be spent thinking about where I want to go and what I want to do. Maybe I could look into child psychology. Or pediatric radiology. I need to find something that fuses together my love for kids and my love for science and medicine. Being a teacher would be a lot of fun, but I've invested so much time into science and math courses here at the high school that it seems a shame to let all of that go to waste. What do I do?

It's stressing me out, because I feel like this will determine my entire future. I am already starting to regret the time that I have wasted in high school so far. Time that I could have spent studying, when instead I was just sitting around on facebook or talking to my friends, while wishing for the paper to hurry up and write itself or willing my pencil to just solve for x already. But since time machines haven't been invented yet, there is no way for me to change what I've already done ( or haven't done). So I'm just going to have to take what I have and apply to schools that really fit who I am and what I want to be. I can't mess this up.
