Is this pp depression?

To begin, I have manic bipolar disorder. I’m 3 weeks pp. the first week after delivery, I would cry everyday. I contemplated suicide. Luckily, that has stopped. I don’t cry anymore or think about suicide. I am however, more aggressive. Not towards my baby and I don’t have thoughts of hurting him but everything sets me off. Little things make me just want to punch a wall and scream. When I get mad I also just want to leave, I want to just drive away with the baby. I would never do that to my boyfriend but I get thoughts to do it. Somedays, I feel like I don’t have any emotions. Somedays, I feel more of a connection with my baby than others. Somedays, I don’t really feel any connection. When I leave him, I miss him but not as much as I feel I should. When he’s asleep, I miss him I want to wake him up (I don’t). I can’t explain it but I don’t feel as much of a connection that I feel I should. I feel like a horrible mother because of it. Does this sound like postpartum depression or something else?
