Today's Diary

Today is so bad to me.(This is correct if your using personification for "Today." If it isn't the case, "Today is such a bad day for me" would be better.)
It's because the light on the ceiling of my room is out again. ("Above the room" would mean the floor above!)
I don't know how to install electric lights. What the........!!!!!!!!!! ("What the -!")
Now, I have turned on the desk.(But did you mean desk lamp?)
Maybe this situation would continue on till the next week. :<

짜증나ㅜㅜㅜㅜ흐어어헝허어...

Well that would be a really "짜증나" moment! ㅋㅋ

Hope someone helps fix your lighting!

파이팅! ~
