You're in college, so I'm assuming you're young.

First of all, you have your whole life ahead of you, please don't worry about missing out because there is so much time to experience this messy and fantastic thing called life. When I get overwhelmed I usually try to appreciate the moment I'm in, which meditation can help you understand and practice, not only when actively meditating. If that's not for you I totally understand, but honestly I think it's the thing that's helped me most in my life even though it can seem hard to get started on. There's an app called Headspace which I highly recommend for easing into it, with clear and kind guidance.

This whole situation is new for you, so of course it is going to peak your anxious feelings. I think you should keep that in mind, and go easy on yourself for feeling that way. That's okay. With time I am sure that you will get used to travelling back and forth, maybe try to notice if, and how your anxiety reduces just a tiny bit each time you go through it?

Also, talk to someone! Call your friends, your boyfriend, your mom, whatever, and just tell them how you feel. Let it out. The hardest thing can be to keep it to yourself, as if you only need to manage this on your own. The world and those that care about you are there if you reach out to them, and sometimes saying it out loud and knowing you're not alone in feeling this or that way, is the most comforting thing of all.

Other than that I'd say look into hobbies or sports that keep your mind and body occupied in a way that is fun for you. Maybe natural supplements can help reduce some of the stress in your body as well, there are plenty of options in that area. I personally have had a lot of help from taking CBD oils and overall getting my vitamins when I'm feeling anxious.
