Can’t catch a break single mom

I’m a single mom I work nights as a cna and then during the day with my baby. Me and my ex split when she was a month old and he gave me full rights to her therefore don’t get any help from him. I moved back in with my parents and been trying to catch up on all the debt I owe from when I was partying and being dumb and young. Well it’s come to the point where I need a car and it’s been so hard with all my debt and stuff to not be able to get alone anywhere. I have struggled and struggled I’ve asked family to co sign and nobody willing to help. Guy please what do I do. I am in desperate need for a car and also being able to get things going for me and my sweet princess. Any advice tips please help!!!🙌🏻😭
