Fucked up my viva so badly

Today was my 1st terminal anat prac. Due to so much anxiety and nervous, said shoulder joint instead of elbow joint in radiology, identified tarsals and metatarsals as carpals and metacarpals.. Couldn't identify any muscles in back of thigh, couldn't identify cubital fossa(so easy question right, I even fucked up that). The viva was being taken in dissection hall so even my batchmates know and i was humiliated in front of them.
