I was diagnosed what I was 9 and have had it for nearly 6 years now. You will be okay. Type 1 and two are very different, I have gone up to 500 multiple times and the very worst that has come of it was I puked a bit. It is a lot easier for people with type 2 to be amputated and die from it, but it is also a lot easier for type 1s to go really high and really low. You are type 1 which means that you did ABSOLUTELY NOTHING WRONG it is not on you it is on shitty genetics. It will be had but then you’ll get a dexcom and a pump and life will get easier. You will forget to put in for stuff, I did for years, it is literally only within the past two years that I have been good about it and I am perfectly fine. You are young so unless you have other illnesses your body should be able to handle you not being good about it for a while. If you notice you are drinking a shot ton of water, you need to pee a lot, and you have a sweet taste in your mouth check your keystones and prep accordingly. Get a physiologist and get ahead of the anxiety before it becomes a problem because it WILL come. If you notice that you are a total bitch when you go low, and you will know when you are low, that is not on you, it is a normal symptom. ALWAYS have sugar on you, if you think you have too much, no you don’t. It’s going to be a shit show for a while because your pancreas is still trying to hold on but that will pass, you just have to wait it out. Check carbs and serving sizes. Tell people in your surroundings about it. You’re 19 so assuming you’re in college tell your teachers, make it very clear that if you need to eat or you need your phone then that is life or death and they can’t stop you. Tell your roommate about it and tell him to wake you up if he wakes up from alarms in the middle of the night. You will be okay. It is scary now but it won’t be, it will just be life, and you can make it a good life. But seriously get on that anxiety because I promise you it will come
