It is not a bad thing.
I cry when I am upset. I cry when I am (too) happy or moved. I cry when I am scared and afraid.
I used to very very ashamed of how emotionally fragile I seem.
I even tried to kill any emotions I have in me (during JC), because it made me much more efficient in doing work.
But it also make me mechanic.
"Heaven knows we need never be ashamed of our tears, for they are rain upon the blinding dust of earth, overlying our hard hearts."
- Charles Dickens, Great Expectations
