Hey, little_windmill. Sounds really stressful. I definitely think it would be a good idea to talk to a professional about this. There are therapies and medications that have been very effective in treating anxiety like this.
Is your college far from home? Does it have a counseling center or something like that? (I'm not sure where you are, but most colleges and universities in the US have counseling centers for students.) Perhaps you could contact your college now and set up some appointments, so you'll have some support right away when you get there. Or, if they don't have a counseling center on campus, ask them about other options in the area. If whoever you talk to can't help you, they should be able to refer you to someone who can.
I know you didn't specify that you have
social anxiety issues, but you might check out our
Social Phobia thread anyway.
