Hay, I totally get this feeling, sobrang common sa amin mga nanay, lalo na pag night time and the house is quiet after taking care ng two babies all day, parang your emotions just hit different. A few of us sa mom group namin experience the same thing, especially when our husbands work away, and honestly it sounds like postpartum loneliness mixed with the adjustment ng suddenly having him around and then missing him again, your body and emotions got used to his presence, kaya when he's not there at night, the hollow feeling kicks in hard. Since the babies are still so young (1 year old and 5 months!) and you've made a big life change stopping work, I'd really encourage you to check in with your OB or a counselor about how you're feeling, it might be postpartum-related and they can help, because you deserve support too, hindi lang ang babies. In the meantime, maybe try connecting with other moms in your area for night chats, or even voice calls with your husband bago matulog para may comfort, because this feeling is real and you don't have to just push through it alone.
