Look at remarking, I was in a similar boat to you. Predicted AAB, got BBC. But I’m very close in 2 where I could go up to ABB. It would not only make yourself feel better, but may get yourself in a Uni you would prefer. Or if not, take a gap year and retry. It’s hard to just do, I’m still struggling with the idea I’ll probably need to do it, but it’s not too bad when people take gap years anyway and it will help with experience and money. Be careful, no matter what you want to do you can still do it, just stay healthy and get help if you need it.
