Anyone else feeling absolutely defeated by postpartum life?

My baby is 12 weeks old & Ive gotten the hang of the everyday tasks pertaining to my baby, but I still feel like tomorrow is impossible every single day. I feel like the actual acts of feeding, changing diapers, burping, swaddling, & putting baby to sleep are easy when I’m doing them but I dread them when I think about doing them in the future. I feel completely defeated thinking of how many days of these tasks are to come & how new ones will be added as baby gets older. I love my baby with all my heart & I take care of her without hesitation or complaints, but motherhood does not feel as rewarding as I had hoped. I don’t look forward to the future anymore. Btw yes I am diagnosed with PPD & I am on medication for it.
