I don't think it matters where you come from or go to - being somewhere new is always going to be tough at first. I'm sure just about everyone on the forum has felt the same way you do at some point in their Swiss adventure - but it gets better. Look at it this way, at least you have someone who knows the language, knows the place and how things work - you're actually in a better position than many others here! Get on a train and come to Wed night drinks at the Talaker - you'll meet more people than you'll be able to remember, and if nothing else, meet a couple of people who won't replace your friends back home, but may be going through the same thing, and can share an email back and forth.
