How do you move out on your own

I was married he passed away. I was young eighteen he was older he knew everything I knew nothing I had no job nothing we were renting a house together I had to leave and move in with my parents I didn't know I was pregnant until later even my doctor was surprise because my abdomen was flat

I had the baby but I want to figure out how to move out on my own.

All I have is myself and this baby I'm not sure where to begin

I live in the USA I'd like to be self sufficient reliable on myself and have a better living situation any single mothers out there how did you make it on your own
