Hey , welcome to the forum , I'm a tiny bit older than what you have mentioned , I'm 22 and have had diabetes for 15 years now .
Always about to chat , I was very lucky and had a very supportive family , but I think no matter what age you was diagnosed nor how long you've had it , there's always new challenges around the corner and I think everyone struggles with diabetes . But we all just have to do the best we can .
I always say to myself that I work along side my diabetes and never against it as that combination wouldn't get me very far health wise .
But it can be difficult , just try to learn as much as you can about your diabetes then you will feel In control .
Take care
