I accidentally submitted the wrong coursework and am feeling very depressed about it.

I'm in my 4th year of my Integrated Master's and had been maintaining a first division for the last 3 years by working my absolute best. Well, in my final semester, I just received marks for a coursework worth 40% of a module and it turned out I got a 0 because I had submitted the wrong coursework (it was for another module). I am absolutely gutted about it because this will most definitely lead me to lose my first division and I feel like everything | worked for is now worthless. I had emailed my lecturer about it and showed some proof by showing screenshots of the timestamps of the files related to the coursework and none of them had been edited once after the deadline. The lecturer was very understanding and they told me that they will give me a potential mark by next week but it's on the board of examiners to decide if I'm granted that mark or not. I don't know what else to do and whom to ask for more help. In case the board decides that I should not be granted a mark, is there anything else I can try to salvage something out of this coursework? I had worked very hard on it and I understand that this is fully my fault but I really can't imagine losing my first division over a mistake like this. I feel my degree certificate will be a constant reminder of my mistake and it's making me very depressed.

do you have a director of studies or academic adviser you could talk to? I'm sure your reputation as a good student will help you here, and hopefully the board of examiners will understand... maybe ask the lecturer to explain your record as a good student.
good luck

I checked the academic regulations and unfortunately, I believe all the modules are counted towards the grade. I did the maths and it turns out that I need a 65% overall in this semester to still qualify for a first which might be doable even with a 0 in this submission. I talked to some of my coursemates and it turns out one of them had the same issue and in the end, the grade for that coursework was not counted and the rest of the assignments/exam got more weightage. I have been suggested to talk to my student union and apply for some special considerations. I will do that immediately on Tuesday,
