I’m a thirteen year old guy and I’ve had t1D for almost a year. Sometimes I get really upset because I don’t know why I have it! No one in my family has it. Most of them have type two. And they keep telling me how to do everything and that I need to go on a no carb diet. And on top of that I have no friends and I feel like my life is falling apart. Someone find a cure and fast! 
I completely relate. Everyone here has/does! Here's what got me through it- as stupid as it sounds- get on youtube. Look up videos about t1D, they are more than inspiring and helpful. Focus on changing your perspective from "Why me?" to "Why NOT me?" A friend told me a few months ago, (he was diagnosed while we were in sixth grade- we're seniors now) that if he had been the only t1D in our class (and school for that matter), he wouldn't be here today. My co-diabetic presence saved my (now) best friend. I don't know you, and I don't know your views, but God has gotten me through it too. Sam is not the only situation that I'm THANKFUL for Diabetes. I am awesome in math, I persevere because I know I have the strength, and I have made friends I never would have because they were different. Without Diabetes, I wouldn't be the person I am today. There will be struggles. I wont sugar coat it. haha *no pun intended* You will struggle every day, but I promise, it will become a habit and you will feel normal. Remember God is in control and He has a plan.
Only about a third of people who get type 1 diabetes have the disease in their family. Most of us don't.
A lot of times we think that perfect is normal and that bad things shouldn't happen to us. But that's not reality. Different people have different challenges in their lives. The older you get, the more you realize that.
While it's hard having to take on diabetes when you're young, in the long term it will probably make you a more well developed, compassionate person. People who don't have struggles in their lives usually are self absorbed and not much fun to be around.
Sorry to give you such a mom answer. I know you're frustrated and just want diabetes to go away. I used to feel that way too, especially as a teenager. But as I've gotten older and started living my life it's not as big of deal and definitely isn't the end of the world.
I know how you feel, man. I felt that way at first, but you have to learn to accept it. Sites like this help because you can connect with other people with type one diabetes. It was a year since i was diagnosed on Sept. 25. What sucks is that no one else in my family has any type of diabetes. So i can see how you feel.
It's a drag, isn't it? I was dxd when I was two and never knew any different. I was also the only T1 in my family. It's tough to deal with family trying to tell you what to do. Remind them that you have a different disease. Use words like "lupus" and "rheumatoid arthritis" (these are both also auto-immune diseases). They will probably take you more seriously and realize that what you have is not the same as what they have.
As for why me, you have already heard the answer. It's "why not me?". Anyone can get it and there is no rhyme or reason for it. You didn't do anything bad or deserving. Excrement happens. The good news is that if you work hard, you can live a long, happy, successful, and fun-filled life with this disease. It's just a pain in the butt (literally as well as figuratively).

All of those answers are awesome!!! I’m new to this site and reading all of these posts and responses makes me feel like I’m not alone anymore!!! Anyway, I was diagnosed 2 1/2 years ago and at first I had a really tough time with it…my blog sugars were alright and usually in check but the whole mental part to the disease really got to me. I was missing school, spending half of my time when I actually did go to school in the nurses office crying. It was a really hard time for me. But I would have these talks with my dad (also a T1D) and we would sit cow and talk about how much it really does suck. But then we would talk about all of the good things! How it doesn’t have to slow you down! You can do anything you want to with diabetes! And we tend to be some of the healthier people around! 
after these talks I got into that mindset of “Why not me?” And tht really helped me! Now I think of it as more of a blessing than a curse! I think of all of the cool experiences I’ve had and people I’ve met and I’m so thankful!!
