Grades make me wanna kms

I absolutely hate it my math grade sucks and if I fail I’m getting kicked out of varsity I’ve literally worked so hard towards everything and my grade just ruins it I tried so hard in managing everything even my schedule my friends can’t even support they just laugh I genuinely don’t wanna be a disappointment to my family or even my teammates I feel like I’ve really let down everyone including myself I geniuses don’t know what to do.. my grades aren’t completed yet and I still have a test to redo if I really fail thsi test it’s the end for me and I don’t want that I really don’t wanna let down any one but I already have. I’m crying alot and I’m trying ny best to focus but I’m really stressed and upset I’m not sure how to feel rn
