I am going to kms

I swear if I do not become doctor when I get older I am going to die because that is my dream career and I've been wanting to become a doctor since I was 4 but I am a Junior in school now and I'm terrible at math and I have an F rn and the end of the quarter is Tuesday so I'm freaking out so I hope we have a test Monday so I can study for 6 days and I can at least get my grade up. I want to cry so bad but the tears just won't come out that's how freaking unemotional I am. I am going to faint. I hate math but I really need to pass it but I am so pessimistic about math and idk
