I’m sorry if it might be wrong to say here but I need to open up about this.
I am from southeast asia and I’m into my 2nd semester of my masters program. Even though I admitted the English-taught program, there are only 4 foreign students and 3 of them can speak mandarin to a point including me.
Since, the start of 2nd semester, I’m struggling with masters thesis research and burned out mentally, but I try to keep up with the studies and assignments.
Last month, while I’m getting better and progressing well, I mentioned my struggles to my advisor during the meeting but she told me that I lacked motivation and vision. She later advised me to approach another professor for an advisor role. Later, she started to mention she has a high standard for her students and mentioned the names of some professors in our department and said their standards are low.
I was also a teaching assistant for her EMI class. The thing is I was the one who always contacted the professor the structure of classes, what should be done, and ideas on class activities. At the time, she said it was a good idea and we should do that. Just 2 days ago, she emailed me I was responsible for the lack of motivation from the students for compulsory reading when it was clearly mentioned in the curriculum and explained to everyone at the 1st day of the class and also mentioned in the same email to terminate the supervisor relationship with her and find a new advisor.
I personally feel that she is not willing to communicate with me. I realize on several occasions during gatherings of my (former) research group that she would say friendly things to my classmates and have conversations with them but not to me (that was after she signed to be my advisor and long before my struggles began).
When I mentioned about my problem with my advisor to my Taiwanese mandarin teacher, she finds it absurd and told me that if the advisor has already signed and accepted you, she should not just say and do like that.
I don’t know what I should do for my next step. There’s only one professor in my department who has available slot to accept a new student but we don’t have the same research interest.
