English diary ( I hope someone can help me the to (alter) correct my writing )

Today is a typical saturday.There is nothing special that happened. Because today is weekend (so) we don''t have to attend class. When I wake up in the morning I find it's dark outside, even if it's already 7 o'clock. As I look out the window the weather (is) looks not very well  so good. The sky (looks) is grey and dusty clouded and I can't help worrying that whether  if it will rain or not. However, the fact is that I don't need to worry about it at all because the sun comes out at about 8 o'clock and it's rather hot at noon it becomes rather hot. 
Every saturday I get up and then go to the canteen to eat breakfast with my good friend-----fisher. She is (a) very friendly and honesty person. I like staying being with her. After (the) breakfast usually we go to the library (and) to study there. Today there are so many people in the library, we (find) discover that our often sitting position regular seats are taken by other people. Therefore,(we have to find other seats) we need to look for other seats.
We often go to eat  lunch at 11:30, but today fisher receives a short message that says that her express delivery has already came arrived and she must  go to the east gate to (receive) pick up theis express delivery. So I accompaniesy her to (fetch) collect the express delivery.

Well done !
