This may shock you, but not everyone loves school Shabbosos. Divide it into parts mentally so the whole thing is easier to “digest”. If you get stressed out, and doing your own thing (reading, sleeping) isn’t an option, think of a funny story or picture yourself at home relaxing. Unless you have reason to think your friends will understand, it’s probably better to avoid the whole topic.
Hang in there, you’ll make it out ok. 🙂
And the ones who aren’t- should be.
