I have 17 Animals in risk of life, and i dont know what to do

Hi, im a man 21 years old. I live with my grandparents for 5 years now. They always had a lot of pets and that never was a problem, till the age get then. My grandmother is slowing losing her memory and her ability to move, always complaining about Pains, but still live an ok live, my grandfather is an acooholic that dont do any treatment or want to make better of It since "he is a man" and "that is what a Man do"

The 17 total animals are 5 Yorkshire Dogs, and the rest blind cats, they dont receive any treatment, baths, Vet, fur cut or anything like that, their fur is always dirt with fezes and piss, and since the cats didnt learned to use a litter box, they also contributes to the mess.

I took Care of these Animals for a Lot of my time for now, but im a Brazilian doing college, and working at the same time, i almost dont have time for this, and its making me Crazy.

The Animals arent take care besides its food, and water.

Im tired of smelling as urine and fezes, im tired of not having time to take Care of myself or rest at ALL, im tired of eating food and having to pick the maggots out of It.

PLEASE, what do i do

I alr posted this text in another subreddits before, since the last time, i reached an ong next to my region to see if something was made out of it, and it didnt work, they never replied me back, and i cant find any other place
