You can still go visit your friend. It will reduce your fears and comfort you by seeing she's okay. And then you will also gain comfort by simply being in the presence of someone you love. Why don't you create like a little camping experience? Bring hot cocoa and maybe marshmallows? Go all out and bring grahm crackers and chocolate too for S'mores! Or simple bring some nice soup. Can do tomato soup and grilled cheese!

So many things you can do. And it's taking care of not only someone else, but yourself. You'll enjoy it and your LC will be proud of you for doing it.
