I reached a breaking point tonight

My five week old has been resisting naps and being fussy non stop. All of her needs are met and she simply won’t sleep. I feel like I’m rocking her to sleep 24/7. No break. She doesn’t like the car seat, or the carrier, or the bouncer or the swing. Nothing. Even cries in my arms. Tonight I was rocking her and sobbing. Then my partner came home put me in the shower and took over. I was sobbing in the shower for 15 min. How can I do this? I’m also ashamed that I don’t want rock her any longer. I’m just so tired. Long night is ahead of me and I don’t know how I’ll make it through.
