Quote From jojo:
I feel that since I've been studying in the UK my confidence is going down. People are so cold and difficult to interact with. My phd hasn't helped either. The never ending critique and appointments with people who can't get past my not being British when dealing with isses I raise doesn't help either.
:-(
Don't like it, leave. You haven't actually raised any issues, just change in culture. You should be glad you got a PhD when many haven't. Anyway there are international socs at unis. I find some people have been cold towards me also and I'm British. Oh well, I'm better off not being friends with them.
