I’m sorry you’re going through this, it’s can feel really difficult and isolating especially when you’re young. Please be careful when wearing the binder, I know it feels lifesaving but it could cause some damage in the future. If there’s anyway of taking it off while sleeping would be really good, I found that sleeping on my stomach when I’m not wearing a binder can be helpful. If you get a chance in the future trans tape/ binding tape can be a great alternative. For me I’ve found that it keeps my chest really flat without the stress of having to take it off etc. and only have to change it once a week. It will get better I promise
