I don't know if it would work for you, but I felt that way with our first. I didn't know it was PPD until after I had my second and could then see the huge difference.
But, when my husband and I were getting ready for bed. I told him I needed him to hug me. (standing up, not in bed) I would let myself open up and I cried and cried and cried. I never could explain it to him, but having him hug me while I bawled made it so I could make it through one more day. Honestly, I don't remember how long I felt like that or I needed him that way. I told him I couldn't talk about it, I just needed to cry.
