You are currently just on a 2.1 (60.2) . You have 70/120 credits of unknown marks. Your degree class is very much in the air but if you do similarly (get a 2.1 in your dissertation and one 20 credit unit, and get a 55 on the other 20 credit unit) you still are very much in with a 2.1 chance.
I know it's easier said then done, but you really can't do anything at the moment so try and take your mind off things and not worry.
