How long on average should I expect it to take in order to stabilize my life and get back to progress?

Daughter is almost 2, CS is 1/3 of my take home pay. So it’s not going anywhere for a while. I’m currently staying with a relative, but after doing the math on my finances, if I wasn’t staying with a relative, I wouldn’t be able to afford rent and utilities after my car payment and CS.

My pay is decent for my state and education level. But I feel stuck like I’m running in place. I’m able to put away savings, but again, if I were to try to go it alone I’d burn through savings within a year.

Think I’d be used to struggling after providing for her and her two kids while she didn’t work for years, but I also had a $425/ month mortgage and everything available right now is $700-$1200 a month.
