Ay mama, 5 months pa lang kaya totally normal yung stress and anxiety mo lalo na if exclusively breastfeeding ka pa! A few of us from my mommy group, parang months 4-6 talaga ang hardest mentally kaya nag-worry din kami doon, pero sobrang importante na sinabi namin sa doctor namin specifically ang constant headaches at anxiety mo kasi hindi dapat ganyan lagi. Try mo rin mag-check if you're getting enough sleep between feeds (alam ko mahirap!) at staying hydrated, pero mama please schedule a checkup with your OB or PCP para ma-rule out postpartum depression o hormonal imbalance, you deserve to feel better and they can really help! Sending you so much love, FTM life is tough pero you're doing amazing na!
