You're definitely not the only one to care about what people think of them. There's a whole bazillion dollar industry dedicated to making sure that everyone worries about what people think of them (media). And another gazillion dollar industry that does quite well with the fallout (pharma). Don't go worrying that you're engaging with society in the only way society has trained you to. It's sure as fuck not your fault.
It might not be my fault to be in this position, but it is my fault to stay in this position. I think the #kidstable tag sums it up pretty well, it's part of the transition from the attention seeking child state to a more stable and more subdued adult state. It's not a required transition, but it does open new option both within and without.
