Overwhelmed

I feel like a terrible mom right now... I’ve been trying for an over an hour to get my visibly exhausted 2 week old to sleep. He won’t stop crying. My SO is out of town and it’s so late I can’t call anyone to help. He falls asleep in my arms while I rock him but as soon as I lay him down he’s up and crying again. I finally had to just lay him down and go sit on our deck. Idk what to do. I’m tired I’m hungry. I just want to curl up and cry
