Is it normal to cry simply out of frustration? I find myself doing this far more often than in response to anything sad. The 2 most common reasons I cry are trying to do something and getting frustrated or failing, and wanting something and not getting it. Kind of childish. I tested as an INTP. Is this typical? I have read that INTP's are very concerned with failure. Is this most typical of some other type, and what types are likely to do this?
