So I had written quite a few drafts for my personal statement and thought it was time to have it looked at by an editing service. The first editor I got did some massive edits. He never changed the message of my personal statement, but he made enough changes that I thought it seemed kind of fishy. So I went through and made changes to fit my writing style and kept things sounded like something I wrote and didn't change the meaning of the essay. At this point there are roughly 4 sentences that I kept of the revisions the editor made. I thought my personal statement was good and didn't think I had plagiarized since I was using an editing service that had been vetted so heavily by other premeds, so I went ahead and submitted my application, but I am worry I plagiarized by incorporating the revisions the editor made. In fact a couple of those sentences expound a bit more on idea I had brought up. What should I do? Did I plagiarize? I am really close to pulling my application and thinking of reapplying next year. Should I just email AMCAS and AACOMAS about it, with a new personal statement?
