I suspect she is embarrassed to have messed up so badly and really was ready to toss it. I can understand that. It is easier to mess up with a stranger than with a friend. It shouldn't be, but it is. (or at least it is for me...) She needs to start a new project that is guaranteed easy...and a small project. She has already learned a lot, now she could just learn a little at a time. :)
...I just reread this and none of it may be accurate....just me trying to put myself in her place. You are a good friend, and she certainly needs that.
