Some advice being a single mother

I’m currently pregnant with my 3rd child and will be a single mother due to their father choosing a different life and not being involved at all. I’m 24 and just curious as to what other single mommies do for a living! I had to move back in with my mother for the time being, but am hoping to get out ASAP. I’m currently working as a personal shopper for online orders at a grocery store until i have this baby, then planning on getting a much better job but am curious as to what other mommies do to be able to afford their own house/apartment, car, bills, kids, etc.
