Guilty

Today, I went to do PP with my 1st year, 2nd semester friend, Mei Xin. I had done my PP but I was so guilty as I said that today both my friend and I will submit the PP report together but in the end, only me submitted as I done within the time that she needed to go home.
I used 5 hours doing everything finished with my friend and I really hope that I do not need to rework anymore. I am very tired. :'(
I did until I feel like I am going to be sick again. Headaches, I think fever is coming right up. I do not feel like eating now for dinner as I still headaches.
But the point is my friend did not finished her work as I always asked her for help. Why? I thought she can finish with me together. I feel so guilty about it and cried in front of her. :'(
Why should I cry? This is no use, man. I also do not know why. Why should I rely in people? Why can't I change? Why I still like this? Why I still like that? I feel like I am dieing soon and do not feel like coming back to this world. This is so boring, tiring and I really hate it very much. :(
But anyway, thanks to my friend, Mei Xin and sorry too about today. I hope that you can do finished today or tomorrow and remember to tell me. :)
Thanks :) and sorry again and again. :(
