I recently got accepted into PhD programs at University A,B,C, and D.
I interviewed with Professor W at University A, Professor X at University B, Professor Y at University C, and Professor Z at University D.
I chose University B.
But now I am having doubts about B and wish to go to University A to work with Professor W. How do I tell Professor X that I want to change my mind and work with Professor W?
I also had additional conversations with Y and Z at C and D; they were pretty helpful and gave good guidance and tips about going to A and not going to B, so I feel even stronger about my decision to attend A over B.
University C and University D are on the east coast, while A and B are on the west coast.
How should I handle this?
Will I be burning bridges with X, Y and Z at B, C and D?
I wish to do my post-doc someday at University D or maybe C so it's important to not piss off X and Y, who both know B very well since the area of research is quite small.
W also knows X Y and Z
