Postpartum depression

My baby is 6 almost 7 months - is it possible for the PD to finally catch up to me. Or is this even PD

It’s just when I try to put her to sleep she whines and it’s SOOOOO frustrating where I get so pissed and just have to leave her in the room & then go back after I calmed down I don’t think it’s fair to her.

I don’t want meds or to see a therapist- but what other options are there ???
