I just can't cheer up!

Renetly, I don't know why that I just can't cheer up. My feeling is moody. Moreover, I'd like to tell myself, I should be careful before talking out, shouldn't I?

learn how to not care about results too much!!

Have you been wanted something very much? The more things you want,the more disappointments you would get. Now I hope myself can learn how to not care about the results that I've taken much efforts too much. I just do my best. That's enough. Anyway, my mood isn't good at this moment.
