You will really enjoy your stay in Denmark - no doubt about that. It will probably be one of the highlights of your life. Should you feel homesick for a while - which is only natural - then seek comfort with your Danish family or your Rotary Club Counsellor. Talk openly about your problems - no matter what they might be. You are a welcome part of us. We will understand you - problems are more or less the same all over the world.
In case you need someone's shoulder to cry on you will find that too. But most of the time you will be happy and the whole time you will see and experience new, exciting things. If you write home frequently - do not forget to write to your home Rotary Club - you will receive many letters in return.
Even if communication is easy and inexpensive, try to limit your contact to your home family as it may affect your exchange experience.
