Feeling so defeated

Has anyone else quit breastfeeding to save their sanity?

I had my second baby almost 2 weeks ago and nursing a newborn with a toddler who needs me too is way more difficult than I could have imagined. I nursed my first for a year, so I thought this would be a breeze but I’m seriously contemplating switching. With my first I was off for 4 months and had zero other responsibilities, so I could just sit around and rest and nurse my baby. now I’m a mom to a two year old, an RN and I have to go back to work in 6 weeks and I’m absolutely dreading pumping all day everyday at work. I have the baby blues incredibly bad and I’m just drained and exhausted, but also so guilty that I nursed my first but I want to stop 🥺
