My husband won’t let me sleep

We have a four month old. Husband gets full night rest, goes on runs, goes climbing, sees friends. I get 4-5 hours of sleep since he was born. I’m not allowed to take a nap. We fight every day in front of our son. I feel awful. I can’t get space. He forces our son on me when I’m crying, when I shower. I begged for sleep this weekend and of course that started a four day fight. I don’t want my son to think this fighting and crying and yelling is normal. I want to die. Everyone thinks my husband is a nice guy. If I was gone my husband would probably be a good dad. I love my son so much and I think he’s better off without me. His family has money and they love my son. I have no family friends money. I have an awful credit score and 10k in debt collection. I don’t see a way out of this. I feel so sad because I had the potential and plans to be an awesome mom, it’s all I wanted. I love him. But he gets a shell of who I am. His dad curses and yells at me for asking for sleep. I wail and it’s the saddest sound I’ve ever heard. It’s uncontrollable. He just tells me I’m hopeless and stop crying.
