I am at this situation and yes I do feel like a fraud. It is an awful feeling. My supervisor thinks that I should thank her because she has helped me so much by writing “my publications”. When I was doing the final editing of my thesis (last month), she emailed me and explained me that I should realize that it is unfair for other PhD students that her PhD students will get their PhDs, because she has written their publications. And I should understand that I haven’t worked as much as other PhD students. Finally, we agree on something. I should have quit. I tried to get along with her too long and then suddenly it was too late to quit. The weirdest thing is that she still doesn’t understand why I don’t want to work with her anymore… My thesis is now ready, but I don’t know what to do. It is worthless for me. I feel like I don’t lose anything if I don’t go to the viva and just move on with my life. So, don’t do same mistakes that I did, it is your PhD not your supervisor.
