having the urge to kms

i feel like killing myself because of school. Nowadays , my grades are going the wrong path. My school grades are going downwards because of all the negative comments from my classmates. All those negative comments from my classmates are affecting my studies not gonna lie. I'm living in depression right now after i found out my parents have covid and my mother is very sick. Me and my family stop eating for dinner since we barely have any food left so basically nowadays we just starve ourselves. I've been getting more skinnier from starving myself. Life is tough nowadays. The reason why i'm venting out all in here is because no one gives a shit about it in real life. I don't know whether to live like this now. I feel so helpless honestly. I can't even ask my friends for help anymore , they will think i'm weak , poor and annoying. I just wanna disappear from this world.
