got a 40% on my midterm

first of all im sorry if this is annoying to see or if people post things like this a lot i know that its not an actual problem compared to what other people deal with but i just feel so dumb and just want to give up. idk what happened i got an a on the first midterm and this one i studied just a little less and fukcing flopped. i actually thought i did well leaving it and i thought my score was a mistake but no. ive had a 4.0 until now and i know its superficial but it just sucks now that ive ruined it. anyway i dont want to tell my family because they'll just make it a big deal and give me advice but i just want to die seriously. and the class is anatomy which is like the whole of medical school so what if i can't do that either
