As an 'oldie' (probably your parent age), I am out of your generation, but I am stilll a pump user.
There are loads of internet sites where you can talk with other teenagers. The pump is not the end of the world, it will give you a much better future for your health, but it will need you to manage it. Yep, some people can get by on injections, but many of us can't. I wish the pump was available to me 25 years ago, life would have been a lot better for me personally.
Don't let diabetes and the pump from stopping you from doing anything. Yes, there will be a few jobs that you won't be able to do, but heck, they are only jobs...apart form that if you take charge of managing this pump, then you can do everything and anything that you want to.
I have sent you a pm......
