I went to a pretty apalling school, similar background, and don't come from the typical Oxford background, so my interview here did kinda scare me and intimidate me. Now I'm here I have had some down moments when (no offence to the people I have met I know you are all lovely!) I just wanted to scream at all the super confident, super smart, super un-intimidated public school types, as they made me feel like I didn't belong. However the longer I have been here the more I have settled in, and come to see that the people aren't so different, and are also often intimidated. And yes it is different to where i grew up, but that is a good thing, even though it scares me at times - once you are there you will come to find the same. Think about your options - you can stay in the area where you grew up, do the same as the losers and dropouts fro your school and never imporve yourself, OR you can take this chance, make something of yourself and fulfill your potential. Worst case scenario if you go and hate it, you needn't stay. And about the relationship thing, people at such academic places tend to be more sexually reserved so i have found, at least compared to the sort of attitudes you and i are used to, and you will by no means be an odd one out or anything, there will be a lot of people in the same boat. Good luck, and try not to worry this is a positive thing! xxxx (ps sorry for such a long reply i just really felt i related to your situation)
