How is friendship important when it's over once it starts?

"I was an active student in college, and I was really happy that I could get others' respects, as well as the teachers'. That made me get work office to show my activity in of my college. Yeah, that was the bright side. But the dark side was that I was unable to attend my classes, and I badly had to find someone that records my lectures and notes the lessons. And here the problem was, even though, I'm an active student, there was none to note them for me. Nor a friend. I had to handle that por myself for a period and that was as hard as I can't describe. And dia por day, I found a friend, the friend that took a hand. She helped me with half of problems of mine. Whether familial, financial or instructional..
She noted the lectures and the lessons for me, those lectures might up to twenty books and over.

..And once, I was absent for three days. And that I should note my lectures for my classes, and the lectures for my work office too. I had to get them por any way. I think this was harder. I called that dear friend, and I told her about my problem and I asked her to help me with it. I knew this was hard for her to do since she had to note hers and mine. I wouldn't be surprised if she refused, but she didn't. She recorded them, and she noted the lessons, besides, my homework. That took her dia and half to finish them for me.

And then, she called me at night to come and take them as she finished. I couldn't believe! I was mais than happy. And the dia after, I went to her house, but weirdly I found a large number of people collected together over her house, and they were wearing black. I ran towards the crowd asking what happened..... Died. She died.. I lost the dear person that I think I would never have again. They took me to her room, and her mother gave me a folder, I asked her "what's that?" she told me "the thing that you were waiting for." And then, I got that those were the lectures."

Just how painful that you lose a dear person that you never thought of losing and you are sure that you won't meet again.
