Full of shit !

Today was still cloudy , my emotional wreck because this bad weather . There is nothing happened , my school life is so boring .
I always know that i'm not a guy who can regulate his mood very quickly .

Another Crummy(1) day!

Today was cloudy again, I am an emotional wreck because of this bad weather.  There is nothing happening, my school life is so boring.

I have always known that I am not a guy who can regulate his mood very well.

Well done!  It is easy to understand what you are trying to say.  Keep up the good work.

(1) 'Crummy' can also be; 'Rotten', 'Lousy', or 'Terrible'.

Your title is extremely crude. It would be inappropriate in any civil conversation. A person would likely use such language in a screaming match or some other verbal altercation.
