One thing I’ve learned from 30-ish years in the industry is that companies change in one way or another and sometimes those changes make the job or job environment lose something that I really liked. The shift to remote is one such change: it may have taken away a critical social aspect of a job that you realize is important to you. I often found it was virtually impossible to resist or change such shifts in my employers, so instead of staying put and being unhappy I tended to just move somewhere new that fit my needs. I think that will be true for the remote vs in office jobs: instead of being miserable in a remote-focused company, people who value in person can gravitate to the employers that emphasize the office experience. It sounds like you might need to consider that: it’s easier to make an individual change to find a fit for what you need than to expect an entire company or industry to adapt for you.

It’s also normal to find such changes unpleasant and sad. Every time I found myself moving since an employer changed in a way I didn’t like, I was sad since something I really liked had disappeared. That’s normal. What becomes unhealthy is clinging to the thing-that-used-to-be and not acknowledging that it changed and likely won’t ever return to what it used to be.
