Home Sick? (20 characters)?

So, there's a cl trip at my school to Catalina Island for 3 days and 2 nights. I really want to go, but I get really homesick. My friends are coming but I still get homesick. Does anyone have any advice on how to keep from getting homesick or control the homesickness? Also, if anyone has any other tips that would be great. P.S. I know it's only 3 days but I get really homesick.
