Any Advice/Input/Thoughts About This?

My gf has said that she hasn't felt like herself at all for a while, a few weeks now. She says she feels off, counts the minutes til the next class or event in the day, can't sit still, feels restless. She wakes up a few times every night for a short while and then goes back to sleep. I'm not sure how else to help her or if anyone else has felt this way and has any info that could help. I'm kinda worried for her.
