Hi rachy, welcome to the forum
🙂 Sorry to hear you've had problems accepting your diagnosis, but it's great that you have decided to get to grips with things and join up here. You're not alone - far from it! Diabetes is something that affects us every day, and getting diagnosed at the age you were is particularly difficult to deal with, since there will be so much going on in your life.
The way I look at it is this: rebelling and not taking the time to test and inject as your should leads to poor glucose control. With that comes ups and downs in moods, feeling tired, grumpy, and probably also guilty, angry and annoyed. It ends up taking more of your energy each day to
not take care of yourself than it would to just do the tests and injections and then forget about it!
What have your diabetes team been like? I presume you've had to transition to an adult team? Do you go to your appointments? Now that you've made the decision to get to grips with it, it would be a good idea to book an appointment with your DSN so you can tell her/him how you have been feeling. They will have seen this many times before so hopefully will be able to give you some good pointers to getting back on track. What insulin regime are you on? Have you done a carb counting course?
I would recommend getting a copy of
Type 1 Diabetes in Children, Adolescents and Young People by Ragnar Hanas and just having a browse through it. It's the best book available about Type 1 and is written in a very positive and informative way - you'll probably discover a lot of things that you weren't aware of, and hopefully that will help you. Please feel free to ask any questions you may have - this is a very friendly group with people who have a whole range of ages and experience of diabetes. Many of them have been through what you have been going through, so if there is anything you are unsure of, or if you just want to have a good old rant about something, fire away!
🙂
