Today is Monday in Hongkong, and the weather is foggy.

More natural to say "it is foggy"

I completed a lot things done and feel like the time is flashing soonby.

Either:
-I completed a lot of things
or
-I got a lot of things done
Either one works.

Actually I have a lot things that still need to be done like writing this eassay.

Also, the most important thing is I am unsure about is whether I have am crushing on a girl.

the expression is "to have a crush". "To crush"="to squish, break"

I cannot stop myself tofrom thinking about this girl.

She likes drivding horses and spends much of her time on studying.

I guess she has a goal, which is to has married wtihto someone and bornhave some kids.

She said I am her crush, but actually every time I send messages to her, she replysies with indifferentlyce.

"with indifference" is more natural

I am really confused, could somebody come to tell me why?

or: could somebody come and tell me why?
