Pgce interview successful St. Mary’s

Hello,
I had an interview at St. Mary’s university and they got back to me and said that I was unsuccessful in the interview.
I asked them for feedback but they haven’t gotten back to me and it was a shame because I wanted to go to that university
I feel very upset now and I don’t know what to do.
I’m scared with my other interviews at the other universities I applied to and it was a shame because I thought I did very well in the interview, and she even reassured me that my reading task was good and that I should book a open day at the university
