Private: Pre-departure- Scotland

I have never left the country before so naturally, I am terrified. What can I take on the plane? What all will I need? What is the temperature like? Will I like the food? Will I get sick? Those are only a small fraction of the questions that are running through my mind. I know everything will be okay in the end, but worrying is just in my blood. I have to just have trust in my teacher and know everything will be handled. It is not like we are walking into unknown territory. These people are normal too.
