Thank you for sharing. I think it is rare that people share this perspective. It sucks that we can't know if your experience is 1 in 100 or 1,000,000.
As a new parent of an 8 month old, I can certainly understand this, even though so far I personally feel much happier than I did before. I think a lot depends on your life situation. With reasonable financial stability, a flexible schedule, and a spouse who (happily) devotes most of her time to the baby, it’s overall a beautiful experience that has given my life a whole new sense of meaning, a depth of love I never knew I could feel, and lots of those peaceful moments pg talks about.
But take away one of those supporting pillars, and I could easily see the stress and responsibilities overwhelming all the positive aspects to the point where it might not be enjoyable anymore.
