Today marks the last day of the Social Media Detox, Brenton High’s fundraising campaign for new sports equipment. At the start of the detox, over 100 students had been persuaded to stop using social media, in ANY form, for seven days. This meant no messaging friends, no posting photos, no blogging – nothing. They had been promised money by family and friends for each day spent without using social media. They were excited. They were nervous. But could they do it

I lasted two days. The detox was more difficult to tolerate than I had expected. I felt like I had lost an arm! Not eating for two days would have been easier!

I lasted four days. On Monday, my classmate and I spoke about what we did at the weekend – it felt really strange not to already know what he had done. We would usually have posted pictures and updated our profiles. Doing the detox meant we had to talk and explain what we were doing and thinking! It made me realise the value of real contact that I had forgotten.

I managed the whole week! At first, I really felt I was missing out. Then, instead of messaging my friend, I went round to her house.
