quietly Do any of these ideas help?
Book an appointment with support services to discuss options at uni - new course?
Write down between you all the options she has - gap year, volunteering, apprenticeship, a gap from course then go back, job in supermarket and a holiday while she thinks, different subjects.
Wait and see how exams turn out - fresh reflection then.
A few private counselling or coaching sessions - pay if NHS are overloaded or too slow.
self esteem appraisal - get her to reassess herself. Focus on strengths.
Get a book ( in my days) or maybe online now where you do aptitude test to work out what are her priorities . Back then, money was not top of my list but creativity was quite high on my list - has changed a bit with a family later 
Get her to exercise - walk. swim, meditate to help bust the stress.
Just be a listening, reassuring ear - so bloody hard when it is constant - I've had that with my DD a few times.
Look after yourself too quietly.
