Back to work 4 weeks after c section

My baby turned a month old on Friday and i have to go back to work on Monday. He will be about 5 weeks. I am just not ready to leave him. I dont have a choice though. I was fired from my job in Oct when I was pregnant with him. And now I HAVE to take this job. I have no choice. I am just so sad that I have to leave baby already. What makes it worse is I am a daycare teacher so I have to lwave my baby to go take care of someone else's baby. I am struggling hard with rhis. I just need a little advice on going back to work. Please no judgment. I do not have a choice I have to make money. My husband is disabled and cannot work so I really need this job. Im just emotional about leaving my infant.
