Heavy rain

Hi there. There is a heavy rain It's raining hard outside. (or, "It's raining heavily") It's so wet.
I don't like rainy days because I can't wear pretty clothes, high heels and I can't make nice hair style wear my hair the way I want.
When I approached company got to work in the moring, I'm sweat I was sweating.
It's terrible.
I want to finish these rainy days to end soon!

I made these corrections to sound as natural as possible. About your hair style, you could also say "I can't have a nice hair style" but I think that sounds a little awkward.
