Help a Mother of 3 Fix Her Car and Get Home

Hello everyone, I'm a mother of 3 teenage boys and we are homeless, staying in our car. At the moment, I really need help to fix my car. It's running hot and needs the ignition coil changed and parts so I can at least get to my sister back home in Chicago. I am currently in Houston, Texas, out here alone; we have no one. Came here to who I thought was family, but that wasn't the case. Currently, I've been sick and can't get meds, food, or anything. Just want to get my car fixed and to be able to just get back home. I would really appreciate anything that anyone can donate to my family. P.S. Thank you in advance.
