First of all anti depressants do take a while to kick in, however, if the one she is on is not suiting her, she must go back to the GP as there are so many different ones available. Took me about 3 different attempts to find the right one for me.
Secondly, there will be a counselling service at Uni and also a support worker for situations just like you mentioned. My friend meets up with her support worker several times a week, maybe just to chat, give advice re career choices or help organising her work load, financial advice, providing emotional support or just to be there to offload her problems.
There really is so much help out there now days, be it at Uni, the GP or other.
My son suffers from Social Phobia and had difficulty actually getting on the bus to college. We approached the college and they allocated him a support worker who actually met him off the bus (discreetly). It is a worrying time when your child is feeling like this and I was told that the best way forward was to provide different options for them and let them feel in control of the situation.
All the best to you and your daughter..............
