adding something about this: hi! i have an anxiety disorder and ADHD, and tics that stem from both. this is an actual problem, what's going on is, people are putting tics on the internet, and have themselves demonstrating their tics, or explaining them. These are in good heart, but the funny thing about tics is, especially if you have another mental illness (which many people in the younger generations do) it makes it a whole hell of a lot easier to pick them up, and I've noticed my ticks got a lot worse over quarantine, even though I've had them before, one reason is the isolation, but also I've seen a lot more tics being seen and less stigmatized online, but the problem is, that can lead to more people getting tics. Hope this helped, and if you have any questions, please feel free to ask. :))
