Hi, you asked for personal experience on how to deal with homesickness. Each individual will be homesick for different reasons.
Mostly it's missing loved ones back home so make sure everyone has a smartphone with plenty of Apps that allow free calls just using your Megabytes, I call my family most days. Some networks will try to block these so also add a VPN to protect your apps being blocked, Hotspot shield vpn is a good one, you can download it off the web or your App Store.
Lots of supermarkets such as Right Choice and Alvihag stock items from abroad especially from UK, even the smaller shops do, I buy Tesco coffee from one.
But the best way to deal with homesickness is to "when in Rome do as the Romans do" and integrate. Make friends with your neighbours, local shopkeepers and don't try to live your life as if you were in Europe, after all isn't that why you left, to find somewhere different?.
