Is crying good or bad?

I went through a lot as a child. and one of the ways I got through it was by telling myself I was bullet proof. and if I was gonna be bullet proof i couldn't cry anymore. so for six years I didn't cry at all until I was assaulted. and all my friends and (trusted adults) told me and still do tell me that it's good to cry. that you can just let it all out when you cry. but daddy always says "crying does not become you" meaning don't cry. and I don't want to be a cry baby or anything either. crying shows weakness doesn't it?

maybe crying isn't such a bad thing after all. I mean I forgot how to cry and now I'm a cutter. :/ but I still have mixed emotions on wether crying is good or bad.

I guess it just depends on the reason. :/
