things you hide ?

I would like to know what you hide about yourself from other people ? Or things you hide about yourself in general. For example ; I hide the fact that I hate myself. Another example would be, I hide that me being molested when I was little still affects me. Another one would be ;i hide the fact that i dont like being around people or even talking to them . These are just some of the things i hide.
I know everybody has a mask they hide behind of, well at least most of them. I'm really interested in what you hidee about yourself ; pleasee comment (:
if you want me to list some things i will , thanks !
