Anak, first of all, sending you a tight hug, ang dami mong dinadalhan at honestly, two kids under five is a lot , especially pag ang second one pa ay very young pa. A few of us moms went through something similar and realized na it wasn't just tiredness, it was postpartum depression or anxiety creeping in, kaya really important na you talk to your OB or doctor about this, yung constant crying, irritability, and difficulty coping ay signs na kailangan ng professional help, hindi lang self-care lang. In the meantime, alam ko it's hard pero try to ask your partner or family member kahit 30 minutes lang para makapag-breathe ka, take a quick shower, or just sit in silence, because you deserve support din, mama, hindi ka nag-iisa dito.
