Have I made the wrong choice?

I need advice. Long story short, I have been in Human Resources the last 3 years fully remote. Human Resources is not my passion. I strongly dislike policies, procedures, task oriented work, etc. I have been frustrated not heard, complained, etc (to my boss).

I was approached by a previous company I worked for in the past (Medical office) and they have really been wanting me back. they have reached out in the past but I have been happy working remote and could never go back to the office. Basically she listened to everything I said, offered me a role offering the exact amount I asked for, two remote days and three in office days 9-3. I accepted the role, told leadership I am leaving, gave my notice etc.

I started panicking as I start Monday that I am no longer remote and will not have the flexibility I have now. I love my current company (just not the role). what will I do when my kids are on school breaks? when I want to help do chores around the house?start dinner early, go to the gym during my lunch, etc. I am giving up all that flexiblity for three in office days until 3pm. I am sick with panick, haven’t slept in three days and regretting my choice.

One of the board members approached me about why I’m leaving and I told them about my struggles. I told them the whole story (not being heard, not the best role for me, etc) and he is meeting with the other three members to discuss finding a role fit for me. But I fear it’s too late. what would you do? Please, any advice helps. I am genuinely sick to my stomach with fear.
