Eating disorder advice

I had a pretty hard year last year, my parents got divorced and i didn’t live with my dad anymore, my cousin comitted suicide and shortly sfter that my brother got in an accident and was lucky to survive, and shortly after that my grandma died. After all of this I just felt really stressed and sad and started developing an eating disorder. I started eating less and less in the end of last year and I’ve been in denial about it until now since the people im closest to are starting to tell me they’re worried about me and that im not eating enough. But now that i want to get better i just find it hard to start eating more. Do you have any advice?
