I'm not sure how to live successfully

I'm a single mother and I had a relationship a engagement but the man I was supposed to marry grabbed me throw me out of the house and I was homeless and pregnant I went to live with my parents and I didn't know where to leave my baby with because in the news there were many local daycares busted for abuse so I'm living with my parents didn't work for three years once baby was three put in a preschool and now I don't know what the hell I am doing

There's a minimum wage job $15 an hour and it's not enough money and I think to myself how much money do I have to earn to survive to move out and I'm not sure how everyone on here says you need to make $40 an hour to survive on your own or make $50,000 a year but how do I get from minimum wage to a higher wage all while taking care of my child and my parents are getting like hurry up and get your life together move out support yourself meanwhile I'm figuring out what kind of life I have making 15 an hour there's some jobs pay $20 but with ss and taxes and health insurance I think it brings it down to $16 how do I get a higher paying job or career

Honestly need advice on how you made it how you moved out parents home and financial advice on this income groceries rent water electricity car insurance cell phone money for mechanic and buy new tires and money for clothing school supplies I just don't know how $15 an hour can pay for a roof

Most jobs like veterinarian technician and medical assistant, administrative assistant, sales associate, CNA, teacher's assistant are paying $15-$20 hour like Walmart or pharmacy technician so I'm wondering what careers and how I can balance work and college what income careers do you have and how did you get there
