Hi,
Well I carried sound a lot if spare stuff in my bag (including my bg kit). However as I went to more and more lessons I got loads of books , so I gave in some stuff to first aid.
I always to my bg tests at break time and at lunch. You get asked a lot of questions : eg " is that a phone ".
Luckily , I have never been bullied for having T1. Sometimes I get some stupid remarks but you just have to brush them off!
Hope this helps ! Feel free to ask me more questions.
