I have been through a terrible experience during my graduate (MS) study in an US university. I have finished it successfully.During that time I have faced severe problems with my mentor. He was not compassionate or co operative towards me and my problems. He often bullied me infront of undergraduates due to some negligible mistakes. There were cases where I was doing some experiments for the first time and I was not successful and he accused me of wasting his precious time and money.He never allowed me any holidays.Even he called me to come to the lab when I was sick and I emailed him about my sickness.He never appreciated any of my endeavors and always criticized my efforts.I could not quit the lab at that time because I had finished significant amount of research work at that time, required for my degree.There was a chance that if I join a new lab, I have to start from scratch.He never took any effort to publish or present my research work.I was also selected to present my research in a conference but when I informed him, he never replied me back.He was so critical that once I was late on a Saturday and he told me that I am not focused and undergraduate students are better than me.He said that infront of all the undergraduates.Despite staying loyal, and working hard, when I asked for a recommendation letter in December 2012 and January 2013, he was very reluctant and he asked if I really need the letter. There were some universities where I applied and some of them said that I have very high chances of getting into the Doctoral program. After receiving his recommendation letter, they cancelled my application and rejected me. In this case, I want to mention that he told me in august of 2012 that I am not capable of doing PhD studies and I do not have required skills. But in 2013 September, he told me I have the zeal to do PhD and he wants me to do PhD under his guidance. I said I am not staying in the lab and I decided to move on. After receiving my degree, he told me if I go to some good school, I will fail and my intellect is very low and skills are not at per although I graduated with a GPA of 3.7/3.8 out of 4. Most of my committee members and other professors in the department recognized my hard work.Fortunately I got accepted to a doctoral school without his reference letter and my committee members provided me with reference letters. Now my dilemma is if my mentor comes to know about this and if he tries to inform my new university will it hamper my doctoral studies? I am in a very depressing situation and I don't want to lose this opportunity after all these hard work. As I always wanted to do PhD and I want to make a new start forgetting the debris of the past. Please help me. I will be grateful for your advice.
