Just/ yet and What I'm doing

Hi Mrs. Başdal!
This is my final homework. My last blog article. I m writing this article.
In fact today's writing is not over yet.This is my job. I m still think about what I should write to the site tomorrow. I am very sick but have taken my medicines yet.I have an amount of water to drink daily, I just finished.

My roommate came to the room. She has not eaten yet. I made Latte for the two of us. He is also a graduate student.She has just finished his own final assignments.  I just opened a new music. Staind-Outside..

I'm not sleepy yet. I'm still using a computer.
I think I'll sleep now.
