Is it normal to be painfully dense and emotionless because of bullying?

So, I live in Philippines and am a native there. When I was still 13 years old, I've been bullied for, like, 9 years straight. As I grew I lost that certain spark of life, and hypnotized myself to think that there's nobody left that I can trust and feel completely empty. These days, I don't really show any emotions on my face but when I do, I tell myself that I couldn't control my emotions well. Being a loner, I spoke to myself most of the time, and spent my time learning how to draw anime and stuff. Some time when I was in high school, there was this girl who called me cute, but I didn't react in any way. My friend overheard and said something like, "Haha, seems like there's going to bea new couple in this class." I had no idea about what he said, then a guy behind me smacked my broad back, saying "you dense motherfucker." So, is it normal to feel emotionless?
