New here... Need to vent

Paisley
My baby is a little over three weeks and I've been EPing since about 5 days pp. It's just what seemed best for us... But now, I think my LO is hitting a growth spurt and he's eating every 1-2 hours instead of 3 and I'm going insane! All you mommas that have made it to 6 months, a year... How do you do it? My supply is decent, but I'm starting to feel like all I do is feed him, pump, sleep for as long as I can, feed him, pump, etc. 
on top of all that, I'm so exhausted and stressed out, I feel like my relationship is falling apart. He's well-rested and happy and amazing at playing with the baby, and he helps when I ask him to, but still it's like every other thing he says or does, I snap at him. I don't mean to! It just comes out and I'm starting to feel like he doesn't even want to be around me. I don't know what to do. Really need encouragement.
