Completely normal to feel lost, Mulan, anybody would after only a week in a new place.
I'm sure it won't take you long to make friends though, as there are very many expats living in Vevey and the area around. I lived there for years.
Just go down to the market in the main square by the lake on Saturday morning. It's a lovely lively place and you'll hear English accents everywhere.
Just pluck up the courage to start talking to someone and you'll be fine in no time.
Welcome to the area, and good luck.

One way to combat homesickness and missing your family and friends is to make them part of your new adventure. Post some photos each week on Facebook and enjoy the comments, answer their questions. With a bit more energy, but not much, use one of the easy blog sites and create a daily journal wih photos of what you are finding that is new, odd, interesting, unbelievable, quaint, cute, strange, funny, beautiful, and memorable. Make it your goal in year 1 to teach the others you left behind and thereby begin to weave the fabric of your new life here. And remember that you haven't lost what came before; but you are adding something new.

Best of luck

We've been here for 6 weeks .... and have pangs of homesickness. Two weeks in I got very ill; I was in and out of the hospital for 2 weeks. One of the days we needed to get a prescription filled - the only place that was open was the Geneva airport. It took every ounce of will power not to throw myself at a terminal.

Since then, I've found some friends (all expats) - we've been to playdates, parks, pools, picnics, & pot luck dinners. However, I was thrilled when my mother in law mailed peanut butter & mac & cheese from home. Anyways, we are now having a great time, but the homesickness hits every few days.

Homesick, I believe everybody living in a foreign country has this sometimes.

In the first 2-3 months you will be a little bit depressed about having left your country. You will feel upset on my things, things which are different here in Switzerland. It seems that everything is worse here.

Then, after 3-4 months you will find some balance. You will find that some things might be better here, other things might be better in your home country. At that point you will accept the differences.

Once you are about to leave the country again, you will feel that you want to stay and that it was actually a nice place. It is difficult to leave the country as it was to leave your home country when you came here.

This is the typical experience of most persons (including myself!). Nevertheless, even after a couple you will still have moment in which you wish to be back in your home country. I think the best solution is to participate in some social activities, be active, talk with other people!
