I'm torn because your cell phone use sounds pretty healthy but I worry others get a more negative experience overall especially with social media.

Also the idea of anyone prior to high-school having cell phones feels odd to me, when I was in school kids worked summer jobs to buy a phone so senior year of high school was a popular year to get into the cell phone game. I didn't get one myself until I completed college and thought I'd need it for work (I didn't). Hardly use it but it is expected to have once you're in your mid 20s making appointments and whatnot. But do people really expect you to have one in elementary school?
