Hi there,
The lead up to results is both exciting and nerve-wracking. I've been where you are and it definetely filled my mind. The university will only contact you once your results have been released - UCAS will let you know your acceptance along with your results.
I know it's difficult but at this time there is no use dwelling. You have done all you can to get to where you are and regardless should be proud of yourself. Try not to worry twice.
Right now you should be taking a break after your hard work. Try meeting up with friends, doing some hobbies or maybe you have a part-time job for some extra money. Try keeping yourself occupied and relaxed to keep your mind off of results - nothing can be done until you know, just enjoy your time!
Most of all take care of yourself. I know anxiety can cause people to let their well-being slip but it'll help keep a positive mindset to make sure you and your body are looked after.
Good luck with it all and hope to see you here soon,
- Sophie (uni of Bath)
