First time I feel like this

Today I just done my FA (Financial Accounting) exam. I feel so disappointed in myself. Started from Year 1 of sem 1 until now Year 2 of sem 1, this is the worst accounting paper I had never ever do before!!! When the invigilator official announced still left 15 minutes, I can feel that my heart beat was almost stopped! I really very nervous and trembling at that moment. My heart was thinking: this time I sure gg and cannot pass my FA paper. I really feel super duper scared of it. Can someone please come and comfort me? I need a hug so badly.
