Uy, mama, I hear you, one month pa lang and you're carrying SO much na. First though, please talk to your doctor or lactation consultant about those flat nipples and what's really possible for you, okay? They can give you proper guidance.
But honestly, ang bigger concern here is you're drowning, and your partner isn't stepping up when you need help most. A few of us mums went through something similar, and realizing na we deserve support, hindi guilt, was a game-changer. Pumping exclusively is HARD, your body needs fuel and rest, and your mental health matters too. Please reach out to someone you trust, your mom, a close friend, or even a counselor, kasi you can't pour from an empty cup, and right now you're running on fumes. You're doing amazing despite everything, but you need to ask for (and demand) help. Hindi ka dapat gumagawa ng lahat alone.
