My first girlfriend in highschool had severe anxiety and was so incredibly quiet and shy. It was so tough cuz she was a genuinely sweet and caring person once she opened up to you. I was extremely surprised to learn her family was nothing like that when I met them. Until I met her dad, and he kept calling her an idiot, and stupid, and useless. Then I understood why she never wanted to say anything. Every time she opened her mouth she was criticized by her dad. This attitude towards your own kids is insanely damaging.
