PPD😭?

Elizabeth
I just had my baby 6 days ago. I thought I felt fine but in reality I just want to break down and cry. I feel like I am in this funk of sadness. This is my first baby and I already love him to death. my problem is I'm stressing over breast feeding 😭 I didn't think it would be this hard on thought it would just come natural to the both of us but i was completely wrong. People are making me feel like such a bad person for wanting to do formula and milk. The reason for wanting to do both is because when I breast feed I feel like it doesn't satisfy his belly because rite after i feed him for about 15 min he gets so fussy and wants more and when I tried formula it got his belly full and he finally pooped good. Which by the way he hasn't been pooping good either it's like the only thing he does is shart. Anyone, does this get any easier?
