Life over after kids.

I am so excited to be pregnant with a baby boy. I got married at 19 and pregnant soon after and I don't regret it at all. I love my life. I love kids, I've grown up with tons of siblings and cousins and babys so I know exactly what I'm doing. But I know it's different with your own child. I'm so sick of seeing all these posts about how I'll never sleep again and my life is over and I'll never be able to enjoy anything again. Like seriously, does anyone have anything positive to say? It's starting to scare me a bit. Is it really that bad? I want to hear your happy experience with motherhood!
