Ate, absolutely not, you're a good person who's just running on empty, which is completely normal! Honestly, wanting time to yourself, a massage, or just uninterrupted sleep doesn't make you selfish, it makes you human , and the fact na nag-aalala ka pa if you're a bad person shows how much you care. What I've learned from my own chaos is na you can't pour from an empty cup, kaya those wants of yours? Valid na valid, maybe talk to your hubby about even 30 mins a week na your time, or a quick foot massage from him while you breastfeed (sounds weird pero trust me haha). That said, with the late period, the exhaustion, and feeling overwhelmed on top of everything, check in with your OB if you can, baka postnatal stuff or hormones, plus you deserve proper care. You're not a bad person, mama, you're just tired.
