麋鹿不迷路

At school now, doing my group project report.
I was asked to redo my part because I copy and paste it directly from a website.
(a kind of. I just changed some words. The sentences are basically the same)

You don't know how hard it is for me if I already have a complete description
and have to rewrite it again with my own words.
I will never feel good with my own writing.
At last, the results is, my part is almost the same as the article on whe web.

This is really very frustrating.
And one of my group member made me feel worse.
She is professional and fast, doing a lot of work.
So it looks like I am doing a little things and even can not do them well.
Then she looks unhappy about this.

This is the first time I feel that I am hurt because of other's attitude toward me.
I've been in a very bad mood since yesterday evening after our meeting.
Don't know what I can do for this...
