There is an old expression: "can't win for trying". Are you sure you are in the right field? I'd start there, first. If you think you are, then ask yourself if you are at the right school. The comment about popularity should be taken at face value; a professor trying to make a point, not a personal criticism. I work with someone who talks to me like a dog and I realize it is her own twisted mind talking, not a correct evaluation of my character. I bring this up because if you think you are in the right field and the right school, then overlook what you think is some professor's peevishness and express appreciation for appropriate help and constructive criticism. Some professors think it is okay to abuse students. It isn't okay but it also isn't really personal. It's past time that you had a talk with someone at your school about your specific concerns.
