Dude...frankly speaking there are lots of grammatical mistakes in your paragraphs and the whole essay does not really make any sense.
There are lots of junks in your paragraphs that can be deliberately omitted.
Try to make a plan before you start writing up your essay, and most importantly, do not write them up like you do in chinese.
Here is my suggestion:
I did not attend the PR lecture this morning because I did not feel like seeing someone in that class. I regret to have chosen this subject(or just use course) since she(try to explain who she is) is taking the same subject as me too. This lecture has become a pressure for me from now on.(or you want to say I do not like this lecture anymore?)
I was going to read some notes in my spare time in the afternoon. However, I ended up filling in colours for a picture I found on a desk. I finished filling in colours for the picture at my Chinese History lecture in the evening. That was really silly .............
Hope it helps
