@ArpanaR When I was a teenager I was exactly as you are saying, couldn't cry no matter what.
Maybe it was pride, or maybe I was just cold, I'm not sure myself
After that time passed and I experienced a lot of things, both good and bad, and I myself tried to change that part of me.
The result was now a days I end up crying for anything XD
it's like all those years holding back made today's tears overflow ;p
