What should I do? Doctor or Engineering [Or even something else?]?

Ok so, I'm sort of at a loss about what I want to do with my future. Ever since I took Biology last year [grade 10, a year earlier than when I should normally take it.]; I've never been so fascinated before with the human body, how it works and it's anatomy. I did really well in that cl as well. [92%/A+]. After I took that cl, I was extremely keen on becoming a doctor, trying to obtain as much information about it as I could and work my way towards it. Currently, I'm taking advance placement chemistry and physics and I am doing well in those cles as well. [93%/A+ in Chemistry and 94%/A+ in physics.] Mathematics is pretty much my own brand of heroin as I do it for fun as well [LOL!]. But anyways, now what I want to know is...is it worth being a doctor? I have half a mind [with a pion] to be one. I want to help people and save lives. But on the other hand...I really want to make [really good] money and still have time to be with family and stick to the hobbies I've had since adolescence in the future. I also hear that doctors have high divorce/suicide rates...but I've never experienced stress or a headache [pively] ever in my life. Perhaps engineering? Since I'm so fad on mathematics and physics. It's really hard for me to decide and I've only got a year to decide. [Yeah a YEAR, but it would make more sense if you saw how indecisive I can be.] Help and detailed suggestions would be GREATLY appreciated. There may be things I don't know about both careers, or even a third or fourth one. Pros or cons? :) Arigato-Gozaimasu! ^^"
