I just thought it was lack of sleep and out of whack hormones but the more I read the more I think it might be ppd

My son is 2 weeks old and I have a 2 year old daughter, I’ve noticed I get irritated and frustrated at my daughter a lot quicker and I feel horrible about it especially when she cries ciz she got yelled at or in trouble for something, then I feel like I’m a bad mom and I worry that she thinks the baby is taking the love so I try to show her love.

My son recently has been more fussy at night and lazy and not wanting to work for milk from the boob so I’ve caught myself getting frustrated at him ciz he’s crying nonstop when the boob is literally there in his mouth waiting on him! I feel bad but I’m so tired and then him not eating just makes me more tired ciz now feedings take longer. I literally get no sleep

My husband and I have been fighting a lot lately, I just feel sad and depressed when I think about our relationship I’m just not happy. And he’s been playing video games and staying up instead of napping so he can help with night duty so I get so irritated at him cuz I don’t feel like he’s helping and when he does help it’s when it’s convenient for him.

We’ve been fighting a lot lately ciz I’ll admit ivebeen moody and irritable

I just feel alone and tired, and this covid shit doesn’t help ciz there’s no escaping to walk around a store etc, and I’m stressed and get anxiety thinking about when my husband has to return to work and then about me returning with the spikes in our state and area. My body feel emotionally and physically drained.

Is this ppd? If so how do I even mention it to my husband with us being on such rocky grounds
