I drop down my tears doesn't mean I'm not strong enough...

I just became so mellow in this few weeks...
day by day, even just for something unimportant, I wanna cry...
and almost all the night, what I do is just crying...
maybe there are a lot of stock of tears in my eyes that I never drop down since a couple of months, and finally my eyes can't hold it anymore and finally... it's became a tears rain... T_T
