3.) Talk to someone else who is with you who might be going through and feeling some of the same things. While it might seem backwards to talk about your homesickness (because then you are thinking about it instead of getting your mind off of it, right?) it can actually be beneficial. The other person, while also homesick, might have some great ideas to get rid of the homesickness that you hadn't thought of. Or they might help you put it into perspective. Or they might just commiserate with you until you've talked through it. Any of these things could help you to ease your feelings of homesickness.
