postpartum emotions

Anyone just super emotional now after having their baby? My son will be a week old tomorrow and I just have a flood of emotions. It's all happy emotions but it's so hard to explain. I fell so much more in love with my boyfriend once our son was born and I just want his attention as much as possible but he's either at work or trying to catch up on sleep which is fine but I just miss him. I'll just start bawling when I stare at my son because of how happy I am. I just get this overwhelming feeling.. I don't know what it is but it's something I never felt before and it's unexplainable.
