Kristy is right. Your daughter needs to learn to "self-soothe" so that she can fall back asleep on her own. She is going through some big psycological changes right now, and that makes many two year olds a bit uncertain. Give her a lot of comfort, but don't always pick her up out of bed when she is restless at night. The first time, walk to her room, calmly say "Shhhhhh, Mommy is here", rub her back a bit and tell her good night. The second time, gently place your hand on her back and say "Shhhhh". The third time, just say "Shhhhhh".
Below are some links for Mom's groups in the San Mateo area. You need to build a strong network of friends to fill in for your missing family. Joining a Mom's group and getting into a play group can help you start that.

You might also call the Netherlands Consulate and ask them if they have any information on where to find others from the Netherlands in your community. Maybe you can even form your own play group!

Good luck.
