Is there something wrong with me?

That is very normal. Thats who you are. You do not have to cry to be upset when you know on the inside you are. Crying is just a sign to show another human that they are upset..... its an expression. I remember when I was a kid my dad got so mad at me and wanted to beat me b/c I said he wasn't sad b/c he wasn't crying. Thats when he told me that a man or women can be deeply hurt and sad and not cry. I never forgot that:)
