Stuck at life

I had a baby right after Highschool. I wanna go back to work or to school but I don’t know how to get life back started after going to interview after interview no one wanting to hire me cause I can only work nights for 5 hrs. Can’t go back to school cause my son isn’t old enough to go to day care I feel so stuck. Like I can’t get my life to get going. I feel so behind and so depressed that I’m doing everything wrong as a mother.
