Lost

I just had my first baby 2 weeks ago. I few so angry but it’s not towards him, it’s mostly at my BD. I feel like I’m the only one who does anything. I’m the only one that changes his diapers or gets up with him in the middle of the night. I sleep when he sleeps and if my BD is awake and baby starts fussing he instantly wakes me up and if I don’t get up fast enough BD gets upset. He barely helps me with anything, I ask him to fill my water and he tells me to do it myself. I’ve never been one to snap out of anger but I feel more and more every day that my restraint is slipping and I just want to scream at him. I feel alone and like I’m the only one taking care of the baby and I don’t know what to do or how to ask for help because when I do he tells me do it myself.
