my mum believes she prayed me an illness

i asked my mum to not eat my food which i buy with my own money which she doesnt even like as its vegan (but if she sees me eat something she always wants it) and she got VERY angry at me, wished me to die and told me how all her prayers of me becoming ill and mentally unwell came true and now i just need to die, then kept yelling at me for the rest of the night. im only 18, does it ever get better. i have such little friends because i spent most my time forced inside and this feels like hell.
