I know it sucks living in the US without a car, I do think it is important to know that it can be done. You are going to have to prioritize though. I've lived carless in some of the most car dependent places of the earth, including the US so I know what makes that a great deal.
I closely know people who have lived in extreme rural areas of the US without a car. You are right that it is possible. But it certainly presented significant challenges. There's a reason why people buy cars in the US.
