Ahhh I feel you, 6 weeks postpartum and feeling like a zombie is SO normal lah, jangan worry. A few of my mum friends masa time tu semua rasa gitu, the exhaustion is real, especially if you're breastfeeding, because your body is literally giving everything away. Try to rest when baby sleeps (I know, easier said than done), makan banyak sikit and drink lots of water, and jangan lah expect yourself to do everything, seriously, just feeding baby and keeping yourself alive is enough for now. If after a couple of weeks pa lagi rasa sangat overwhelmed or super sad, boleh check dengan doctor sebab postpartum blues or depression boleh jadi jugak, tapi most of the time it's just the exhaustion catching up with you. Hang in there, mama, it gets easier!
