For me the problem is that you feel this is wrong, when actually the way you are feeling is very right...
Parenting isn't and never was something that you were meant to enjoy, or be a "fan" of. Historically, and in many places around the world it is/was a practical choice out of necessity that women (and men) made because they had no choice. Not because they thought "Oh won't this be fun!"
In truth, the vast majority of people do not, and will never find parenting to (overall) be fun. And that is perfectly ok, and should be said to every single person who wants to try for a baby. It isn't about having fun, never was, never will be... except for a very small minority who enjoy it basically like they anyone enjoys any hobby or interest.
I don't blame new parents though because it is how we are sold on it - we are lead to believe it is this life-changing fun, enjoyable, brilliant thing, from all the parent blogs/social media posts etc. So then of course you would feel like you aren't normal when you discover the reality of it.
The historical and societal truth is that has never been something that we should do for fun/happiness, instead it is more like a job or a responsibility - You had kids to secure your own future, and the future of your tribe/society/nation. We don't say this any more, but it is still true on a societal level. If we don't have kids, there will be no economy to support us, no one to care for us when we age, no one to hopefully make the world better etc. Society just ends. So just like a job, have kids.
So think of it like that. You have a job, that will take you 18+ years, and if you do it well, hopefully you have created a person that contributes to your family and society, in a way that you will need for the 30+ years you are "old".
Once you forget the idea that you are meant to find it fun, you can hopefully accept the situation as a normal thing, and not feel bad strange about it.
