part of essay,my homework2

This is the first time I've written/wrote such a long essay. I wish someone would correct it if I've made any mistakes~~~
:)

But I wasn’t feeling very sad at the time. because I had a new house, new friends, a completely new environment. I was happy because I could play with my friends after class. Though I miss him, I don’t go to see him often. Only on vacations or some special festival. 
After he was gone I realized that, for me, it’s only going to take me some free time, but for him it was a kind of hope (dream,disire?). A hope (dream,disire?) for me, a hope which (lasts forever?) needs a long time to wait.
I hate myself for taking such a long time to realize that. I feel sad when I look back on the old times.
I remember a spring festival when I went to see him. His body wasn't as good as the old days. He walked slowly to the kitchen and took (picked out?) some bananas, apples, and some candies which were my favorites. And he said: ‘ Honey, grandpa (saved these especially for you. I know how much you like these fruits. /?) reserve it for you specially, I remember you like those fruit.’
I just took it (him/?) for granted.
I never thought of losing him, never. But all of a sudden it did happened.
He didn’t have a lot of expectations for me, but I remember he once said, ('I hope that you will be accepted into a good university."/?) he wish I can admitted to a good university. Although my school work is not that good, I think that my grandpa, if he was still around, wouldn't be disappointed.
I want to make him proud.

(I hope I didn't change the meaning of your story.)
