If you do this, you must arrange these jobs before you go. I've read too many horror stories of students flying half way around the world only to find out the job does not exist or that they cannot legally work in the country they flew too or that it pays far, far less than promised.
Having said that...it's very normal to start to feel anxiety about going to college during the summer before it starts. That may be what is happening with you. Or it may not. If I were your parents, I'd have you see a therapist to talk it out. Even just one or two sessions may help you decide which path is right for you.
