Middle school is so fucking annoying

Sorry for the cursing but, I’ve been stolen of my phone, my whole computer and my charger, and guess what? We all have to have clear backpacks, I hate it so fucking much. I’ve been robbed of more than 200 dollars worth of stuff. Y’all have any suggestions on how to keep my stuff safe?
And for some reason they haven’t stole something else I have which is worth more than any of it.
