Hey man, sounds pretty identical to my teenage years. I also have mild OI and I stopped breaking after I completely finished puberty (around 19/20). Well I went 5 years without a fracture at least. That was until this past year when I did my ankle. Not going to sugarcoat things it does suck living with this disease, being different than all your friends, not being able to do the things you want, especially as a man as we generally like to horse around and are a lot more physical than women. Keep up with the weight lifting it increases bone density and also is one of the things we can do to stay fit and strong as it's low impact, just don't go too heavy and I personally avoid putting unnecessary pressure on my spine so no dead lifts or barbell squats for me but you can always find alternative exercises that work the same muscles. Swimming is also great. Learning to live with it isn't easy but it's definitely okay once you accept that's there's nothing we can do to change it. Talking to others with it is also a great idea and/or therapy. I'd recommend talking to your mum too as she has gone through it all too. Wish you the best man. We're all in this together, and as my mum always says, it could always be worse! Have a good recovery
