*Tbh I'm with the person who said she just has to get on with it. You say she is lonely, scared and homesick. For a start you tell her there is nothing to be afraid of, she is in a room getting all her meals delivered to her, I'm not sure what she could be scared of in that situation? What does she think will happen to her?
onely? There have never been more ways to connect with people, social media, forums, video calls, good old fashioned phone calls, text messaging.
Homesick? Prop up your phone or iPad or whatever and chat with her while you are cooking dinner. Watch tv together. Play a game together.
Send her a parcel with some things from home, art supplies etc for something to do. You can buy books, films etc from your bed these days and get them instantly. There is loads she could do to pass the time, it is only 2 weeks.
What won't help is catastrophising the situation and making her feel like it is worse than it is.*
Absolutely this!
I think we all need to be a lot more pragmatic about having to isolate/ quarantine. It's a major nuisance but it's really not the disaster for most students that some are making it out to be.
Encourage her to set up online contact with the others in her block and also her old friends at home. They could set up quizzes on Zoom, and wattsapp each other etc etc.
Think about any suitable new hobbies she could take up such as geneaology, crafting, art, learning a foreign language, gaming, yoga, meditation, etc etc. Maybe send her some doodling books and pens along with other stuff in a parcel.
I think collecting her and taking her home should be a very last resort and only done if you don't need to stop on the way home, and your whole household can genuinely quarantine for the next two weeks, or longer if it turns out that your dd does actually have Covid.
