Just a question

Is it normal to feel emotionally withdrawn, I don't feel anything, any emotions just goes past me when I'm in public or with my parents, but when I get into a room where I'm alone I just feel like I want to cry, I get scolded for the small things, I don't show it but I'm hurt that only the mistakes I made is seen, even writing this is making me want to cry just thinking about everything that happen, so is it normal? Or am I broken and I just don't see it?
