this is a healthy sign. sorry about the circumstances that triggered your crying - but glad you were able to feel and express that grief.
i have found that "we" often are able to empathize with others in their pain more readily than to feel the pain that we rightfully should be feeling for ourselves. somehow we think we don't deserve to receive sympathy or compassion from anyone - even ourselves.
it won't be long, i'd guess, until you are able to feel the appropriate emotions on your own behalf.
How long, LORD, must I call for help, but you do not listen?
Or cry out to you, “Violence!” but you do not save?
Why do you make me look at injustice?
Why do you tolerate wrongdoing?...
Therefore the law is paralyzed, and justice never prevails....
