I don't know that I did 'adapt', to be honest.
I think people deal with this differently depending on what they think the 'university experience' is, or maybe their perception of what it should be.
I was quite old (mid 20s) so I had friendship groups already, I had local boozers already, I knew the city, and I wasn't preoccupied with making friends because my support networks were already established. This is obviously not the case for students who move away.
So for me there was very little pressure at all and I just ambled about as usual. If I made mates, I made mates. If I didn't, oh well.
Similarly, when I later moved down to Oxford to do a PGCE, I wasn't that concerned about any of this stuff either. I made a few mates down there but literally only still speak to two people from then. I think it's down age and experience.
