I developed a damaging screen addiction that lasted over 10 years.
I started using social media as we know it now when I was 13, in 2009 - I think this was maybe the worst time, as I was one step ahead of my parents and not much was known about the harm to young people at that point. I had been using online messaging platforms and forums from a younger age however; my dad taught me how to use the computer from infancy, and after my parents divorce when I was 8 it became an escape (and something that was consistent between both their houses).
