Hey Anmi,
it is pretty tough to get used to, yes... but believe me you will! frustrating as it sounds it just takes time. i can't say i felt the same way you did (i was ten and kinda excited at learning new stuff) but once you take control and run with it you'll feel great. also yes weight gain is often experienced when you get your bgs more stable... making the balance ever more important, but again, don't stress and take it one step at a time!
