Is it PPD?

I'm almost two weeks post partum and I'm having a really rough time, even though I have a really calm baby.

My son was born 2.5 weeks early, had jaundice, and was a stressful and I had a really traumatic emergency c section which effected my attempts at breastfeeding. Which I stopped doing because he wasn't gaining weight fast enough, his blood sugar dropped and we spent a week in the NICU.

We're home now, but I'm not calming down. I keep obsessing over his temperature, how much he eats, poops, sleeps and I'm having crying spells, panic attacks, mild irritability, and just general feeling like I'm a shitty mom.

I'm so nervous of PPD, but could this be it even this early?
