If having kids is so awful, why do we do it?

[Lilybow]

Pregnant with my first and in my third trimester. The majority of things other mums tell me are:

"You think you're tired now, you will have a shock when baby is here"
"You and your husband will never go out together alone again"
"Your social life is gone"
"Baby will demand your attention 24/7 and you will be desperate for 5 mins to yourself"
"Hardest thing you'll ever do"
"I hope your baby doesn't have colic, you don't want that"

I'm not under any illusions that parenthood will be easy, and i know my life will change, but I'll be honest I'm pretty terrified as apart from the occasional "oh how exciting" comment, people keep telling me how hard/boring/exhausting it is and how my life is over.
I need some reassurance that my life isn't over and it's not that horrific.

Like most things in life there are pros and cons to having kids, and to bring child free.
I did become a better person when I had kids because it made me really consider things I’d not considered before. I take seriously, the obligation to bring my kids up in a way where they can think about prejudice in the world, also I’ve examined why I react in certain ways to things, so I can set a better example. There are numerous ways where I’ve had to examine myself in order to be thh kind of parent I want to be and as a result I am a better person. But that doesn’t mean I was awful before and it doesn’t mean I’m better than those without children
