Scared of my future

I am now a single mother of two. With no car, no money, no job, literally nothing now. I’ve been with my kids father for 10 years as a stay at home mom. And we got into an argument; things gotten taken too far and now he’s saying we aren’t together. I’m so scared of my future. I’m blind in one eye and losing vision in my other and I have no idea what I’m supposed to do. I don’t want to stay in this house with him if we aren’t together. My sister says I can stay with her but my daughter is in school and my sister lives about 40 minutes away. I was saving money to get a car but now I have to use that money to see an eye doctor. Please I need advice or words of encouragement or even opinions on what to do. I regret depending on this man for 10 years. I literally have nothing.

ETA: he said he isn’t going to give me alimony, he’ll pay child support and that’s it. He said everything else is my problem. Also, I’m a type one diabetic but apparently I can’t get disability..
