Do you think that diabetes will get away if i make good diet?

i have diabetes since age 14. now i am 19 years old and i still suffer from it. Frankly, i eat anything that i want and i don't really care. but my parents and friends keep telling me if i eat healthy and exercise regularly it will go away for good.
is this true? can i end this disease for good?
i have type two
i use pills
