Hard agree. I lost everything. Pre kids: working in a startup with long (but enjoyable) hours, lots of travel, conferences, tech meetups multiple nights throughout the week followed by continued discussion / dinner / bar hopping afterwards, music festivals, clubbing until sunrise and time with friends on weekends. If I wanted to do something, focus on something, or neglect something it could happen.

Then I had a child and COVID hit at the same time.

I switched jobs to an org with much more stability, predictable hours, and absolutely devoid of any passion. Combine that with immense sleep deprivation, no child-compatible social network, and society going through its own existential challenges. My mental health was comatose.

It's hard. It's really fucking hard, but you will settle into new patterns that work for you, even if that takes time. I'm now a few years in, have redefined some sense of self, work part time (in the same org, but a properly enjoyable role) and have a tiny human that my partner and I are continuing to explore the world with. It's an inexplainable experience that you're about to embark on. Hope you enjoy the ride.
