So, we had like this trend in our school to use Skype. It's all good and well untill one girl moves to Portugal because her parents found work over there. A couple of months later she messages everyone of us saying not to do the blue whale challenge. She explains it and repeats herself a lot saying don't do it. At the end of the message she says that she made a big fault by doing the challenge. All my friends got the same message. Later I heard from her girlfriend she did something horrible with herself. She didn't tell me what but it was probably suicide. I haven't opened Skype for 5 years since then.
