That's great news!
I've had my pump for over 6years now and I couldn't be happier. It has literally changed my life.
As previously mentioned, you should attend all the information sessions and talk to your diabetes nurse about any worries you have/
It does take a bit of getting used to, but it's not impossible. There will be an adjustment period where you and your nurse will figure out how much insulin you need but if you already change your dose with carb counting, you're half way there.
Please get let me know if there's anything you want to know from another pump user.
Good luck!
