Just got diagnosed with diabetes, when will it go away?

Well turns out ive probably had it most my life and ive been just fine--- my boyfriend got a little spooked when i collapsed while we were out so he basically made me get some testing and yeah it turns out i have diabetes. But i'm do so will it only last a few years or what? Aand what does this mean, ive been living with it for awhile, cant i just keep going like i have been? no needles and stuff...gross! when will it end?
