Feeling blue during feedings

Kara
Anyone else lose their appetite & just feel kinda blue during a feeding? I could be super hungry, but as soon as LO latches on my appetite disappears & I get a feeling of kinda sadness come over me. I love my LO & I don't feel that sadness outside of breastfeeding. & I love being able to breastfeed her. Is this part of postpartum depression?
