Personally, I would have said that you simply needed to try writing without the character of the bad mother. However, your professor, rightly or wrongly, sees the repetition of the character as a problem - whether personally or simply from the perspective of how it is affecting your writing. Apparently, the professor has misinterpreted it as being a personal problem. ree-Xi has given you some good advice. Do go talk to the professor, but try and keep your emotions out of it. Focus on asking how you can improve your writing - that's what you are paying the professor for, after all. Let any personal type criticisms roll off your back. He/she's there to help you with your creative writing, not to give you therapy.
