I'm in same positions left off my studies and talking exams the good thing is they know I suffering depression I get to go in small room and have 15 extra minuets to take the exam which does help. Also I'm going to see mental health advisor at university to explain to him how I have found this semester difficult and confess up about not studying to try see if I can get mentor for next year which I hope I done enough to get into next year even though not done much studying.

What do you need to get exam wise to get into next year like percentage?
You probably have done alright even though you may have left of the studying although it probably doesn't feel like you have.

Best advise try your best with what you done so far and for future seek support so you don't fall into same habits again.
