Hi Chlo,
Sorry to hear you aren't enjoying having diabetes. I hate to say it but I don't think anybody really enjoys the constant testing and needles. It is hard, and I imagine you can still remember the time that you could eat what you wanted, when you wanted, without a second thought. I am sure that you worry your parents a bit and that probably feels a bit strange to you also. My son is now 2 and a half and had diabetes since he was 8 months old.
I gather you have been looking after yourself for a little while now but maybe you could ask your parents to take over again if it is getting a bit much. I hope you are not having trouble at school.
Try to look at your diabetes as just another part of your life. If you look after it you'll find it will look after you.
If you need to let everyone here know exactly what you hate the most you might get some help to make it a bit easier. There is also a Youth Section of this forum where you can meet other kids your age who are going through exactly the same things.
Jen (with a big hug)
