Is this postpartum depression or normal?

New mom to second baby. I had postpartum with baby number 1 (now a toddler) but honestly it’s a blur. New baby is about a month. I’m grieving having any alone time what so ever or anything I do that’s for me (I understand this to be normal), but I’m often just feeling sunk and asking myself why I did this? It’s so hard with a toddler running around who won’t nap and a newborn strapped to me. I often think I could just die and it would make no difference. I can’t think of anything other than being trapped in my house and just being a mom and nothing else foreseeable future

Is this normal? Postpartum? Am I just dramatic? I mean millions of people have multiple children and balance it all and thrive.
