i feel so hopeless

this is probably going to be a mess of a rant because i just finished crying so read if you will.. baby is 2w1d a couple days up until yesterday he was doing so good sleep/feeding-wise and i felt like i had it down and i started to feel better mentally. yesterday just felt like chaos. non stop eating, he didnt nap as much as he usually does, fussing all day long besides maybe 1 or 2 decent naps. didnt want to sleep on me or in the playpen. i just felt like i couldnt satisfy him no matter what i did. i kept it together all day though. we did our nighttime routine (bath, white noise, feeding all that) , now typically on our good days at night after our routine he is fussy until like midnight, well after a chaotic day he was not fussy last night and he had a good nightime routine down, good feeding and diaper changes and went back to sleep easily (very confused) well now its morning. he peed on me twice and spit up like a whole ounce of formula and he usually does not spit up that much and well i bursted out into tears because i can not handle another chaotic day. i know i shouldnt assume how the day is going to go but im nervous and scared and not ready and i really just want him to nap today. i feel so useless i feel like i dont know what im doing i feel like im failing him. i dont know if this is normal or not.
