Overwhelmed

My son is 8 weeks old and I'm exhausted, frustrated, and completely overwhelmed. He's been so fussy and hard to get to sleep. When he is sleeping it's only for 20 minutes. I had to put him on formula bc my milk completely dried up. He eats every 2 hours and it's killing me, I'm so tired. I just need some words of wisdom bc I'm at my breaking point.... I would never hurt him but I'm starting to resent him and it's making me feel guilty/ I have 3 other children and I feel like I don't give them any time at all bc I'm preoccupied with my youngest. Please don't judge me I just needed to vent.
