I am right there with you. You are not alone. I am 10 days PP. I try so hard to fill my day up with little tasks and I too am just so zoned out/uninterested. I look forward to my husband coming home so I finally get interaction. Today I went to get gas in my car, dropped off maternity clothes at the clothing bank, and picked up a grocery order. This was so exciting to me. Even though I was still anxious, and had so many nerves being in the car with a newborn I know this is what I needed to force myself to do. Just getting out of the house for an hour.
Please bring it up with your doctor! There are medications that can help if you think you may have PPD and it's better to get treatment before it gets worse. A doctor can help you determine if it's the start of PPD or something else
This actually sound like the start of PPD. I would advise you reach out to your doctor for help.
