defeated mom. my two week old won't sleep

Dani
My baby will not sleep. He stays awake almost all day. He is gassy, I've don't gas drops, bicycle kicks, belly massage. I put him on his belly and he will sometimes sleep. I know he is tired. He has to be. He is eating well and gaining weight normally. He just wants to be attached to my breast 24/7. 
How can I get him to sleep? I rock him, put him in the swing. Let him fall asleep on my chest. I don't know what to do. I am feeling defeated and I'm exhausted. I just want him to sleep. I know he is so tired. You can see it on his face. He is my first baby.
