I am a type one diabetic and i need HELP!?

Ok here's the deal i am 17 years old and i have been a type 1 diabetic since my eighth grade year and i am now entering my senior year! I have had problems keeping my blood sugar under control for a long time. My doctor can increase or decrease my insulin as much as he wants but my blood sugar is constantly high...i can rarely see it under 200 mg/dl... i am scared that if i dont get help with regulating it i could be facing some serious yet dangerous heath problems in the future that could cost me a fortune. I would like to know if there is anything that i could do that could naturally regulate it or anything that i could do to keep it low, or atleast in the normal range. I will take any kind of advice i could get to get me to live a healthier lifestyle. I eat healthy and i exersise all i can but i still cant get my sugar to where it needs to be. HELP!

What kind of insulin do you take? they have come out with some quick acting insulin that is grate you can take it before you eat to bring down your sugar and it gives you MUCH MORE CONTROL over your diabetis. I used to use just the time released one and it sucked because I could not get it under 300 went to a comb of time released and quick acting and its great. Also after a few months on the quick acting and I find I don't need as much. At first I took 12ml before each meal and bed now it's 5ml.
