Help mommies

Normal lang ba na mag overthink, depressed during pregnancy? I'm not this kind of mom or partner na lagi in a bad mood. I see to it na lagi kaming masaya and yung positive vibes nag fflow in our home. For the past few weeks/mons I feel so much tired, exhausted, umiiyak cause of overthinking.. Kahit pigilin ko di talaga maalis sa isip ko. I'm at 31 weeks na with my 3rd and now lang ako naging ganito 😢
