returning to work after birth

How soon did you return to work after giving birth? I'm a newly single mom and I'm worried about going back to work after having my son. I feel like I have to go back immediately. Like a week after 😩 My fiancé and I split up a few months ago, as he cheated on me - I have minimum money saved. It's going to be hard and fucking SUCK. I've been a stay at home mom for 4+ years before this and am only working part time currently.
