hi and welcome melancholiclife. Everybody has to encounter a new place at some point in there lives. It isn't easy to start somewhere new but just be yourself and I'm sure you will do fine. Try to spot a quieter person and try talking to them, or some1 who is on there own. Start a conversation by asking directions to somewhere, its a bit sneaky but its a good ice breaker. If you start to feel uncomfortable thats normal...people find a new environment stressfull.
Hope you make some friends and let us now how you get on
P.S. dont expect to make loads of friends straight away, it takes time and effort to build up good relationships and trust. Be yourself and I'm sure you will be OK :wink:
