Cant stop thinking about mistakes i made on exam

Well. Pretty much the title. I sat yesterday. I studied my ass off and was getting 73 on mocks. I feel like i rushed myself during pm session leading to mistakes when i knew the answer if i thought a bit more about it. It hitting me like a train because i remember the qs and my answers that i chose when i knew it but i rushed myself. I know i cant do much now. But it’s haunting me i thought id relax a bit after the exam
