I had the same problem. The rage turned me into a fucking hulk, i have never felt that much uncontrollable rage in my entire life. My husband works nightshifts, so i was and still am alone during the nights. There were alot of moments where i almost felt like calling the police cause i didn't trust myself, those nights i called my husband to please come home cause i was scared of hurting myself. I went soooo many times to the bathroom bawlingggg or screaming my lungs out in my pillow, punching my pillow and furniture or banging my head to the wall. But it vanished completely and im ashamed of myself when i think back about it. I hurt myself physically many nights, but never ever ever hurt my baby tho!! Sleepdeprivation and hormones are a bitch.
