I found the story endearing. Your little brother only wanted to be a part of the cool kids!
Also it was the bully's fault that your Vita is broken since he was the one who put it behind the toilet. He deserves a punch in the nuts.
And just saying but... whenever you have a brother, there is no such thing as "stealing". You have to share everything with them! Let's just say he took it without your permission 
PS: Your brother isn't an addict to videgoames. He is just a kid that wanted to fit in with his friends and did it in the worst possible way. This is normal stuff that happens when you have a brother. Mine deleted my 7+ playthrough, 100% complete perfect Chrono Cross save because he needed space on the memory card. It happens
