Be closer
If the relationships are close, you can hug or take the hand. First specify before whether the person is not against it. If he/she cries - give a napkin. Take care: create comfort, cover with a blanket, feed, put to bed. You can say with words: “I cover you with a blanket, you will be warm. I hug you. I stroke your head, I hold your hand. You are not alone with your pain, you are not alone with your fear. I am with you and I am here for you now.
