Well the main thing is your type 2 and not 1. So no insulin for you! Which is fab! :)
But to maintain it, you definitly have to have a lifestyle change.
Honestly harder then it sounds. I've been battling weight for years, going up and down.
But recently i got a wake up call, when i was sick for 3 weeks! I got a really bad urine infection. And it was because i had too much sugar in my urine. :( SO really gotta cut out all the bad habits now. Because i'm only 28 and i really want to have kids some day! And live long enough to see them grow up and have kids of their own!

It's definitly a lot to take in. I was diagnosed at 17. I honestly had no idea, and nobody told me the effects it has on your body, and what could happen to you. I was young and dumb. And i really wish i could rewind.
You'll be alright hummy. Just stick to healthy eating as much as you can! (your allowed a treat now and again) and small portions, and try exercise as much as you can. Are you overweight at all?
