Losing it completely

I am a stay at home mom to my 15 month old son and these past few days have been completely horrible. I'm pretty much ready to throw my mommy towel in. He has been refusing naps. I sit with him for an hour trying to get this kid to nap and he wont fall asleep. If he doesnt nap he wont eat and it just throws off our whole day. I'm over the attitude and I just need a break. He wont sleep in his crib. Nothing is easy with him. Idk what to do but I'm doneeeeeeeee
