Good Morning.
Welcome to the forum.
It is possible that Unteraegeri will end up even lonelier than Bülach
Though through a recent visit to the Swiss- New Zealand club, (

Another thing to do is to get in touch with the "mutterberatung" in your area. (It may be called "elternberatug" now, but i doubt it).
And the German classes. Not only are these good for meeting people, but they allow you to choose your friends, and not just have them limited to the people that speak the same language as you...
Oh.. and hang out here.. its a repertoire of bored, lonely housewives
