Thank you, I actually agree after you explained that something mistake ridden would be more meaningful and personal even. My only concern is if it is too ungrammatical that she would not understand what I am trying to say.
I am only changing two parts, and that is because I should of known to use 大変, so that's not much of a big change. And using ご指導, because I wanted to use it when I was thinking how to write this, but wasn't sure how to use it. Also, can it be said as 「大変お世話さまになりました。」 Or is it really strange to use さま there?
