I had to do that. In fifth grade, I read constantly (much to the disdain of my peers), argued frequently (much to the disdain of my teachers), had enthusiasm over things that nobody else had (much to the disdain of most fifth graders), and I was generally annoying as a result of anxiety attacks (much to the disdain of everybody), so I covered it up for survival. I also never tried to talk to anyone or play with anyone unless they were disabled (had more empathy for them than for most people), younger than me, my sister, or if they were adults who understood my interests. The people in my class even yelled at me when I said, "I don't want a job that pays a lot if I'm not helping anyone".
So, yeah, I had to change, but I feel guilty for hiding myself.
