My mom never believes that I’m sick

I was diagnosed June 2023 and at first she was a little bit caring, but then after she started accusing me of doing it to myself, and when I would tell her that I didn’t feel good she would never believe me and told me that I was doing it for attention. I have diarrhea and vomiting and I told her that I don’t feel well but she keeps telling my entire family that I’m lying and it’s just psychological. Including my doctors think that I do it to myself because of her explicit lies. I don’t know what to do. My mom has made my illness all about herself. In the span of the year. Every single time doctors ask me how I’m doing. She will cut me off and automatically talk about herself and how she is. “ stressed” doctors keep showing her proof that I’m not lying about being sick because the labs show otherwise , I don’t know what to do 😕
