Loss of job, loss of identity

I'm looking for some advice. For the past decade, I've dedicated myself to a career in management consulting. Early on, I was drawn to the field by the intellectual challenge, the opportunity to apply my technical background in a business context, and the allure of international travel. I've climbed the ranks, worked with brilliant people, and gained invaluable experience.

However, the demands have been relentless—long hours, constant travel, and significant personal sacrifices. I've missed out on family events, time with friends, neglected hobbies, and seen my identity become intertwined with my role as a consultant. Recently, I decided to leave my job, feeling burnt out and craving a change, but now I'm grappling with doubt and uncertainty about my future.

I'm worried about my identity without this job, finding a role that offers similar compensation (TC ~170k), and if deciding to leave was the right choice. I don't have anything lined up and I am still employed but mentally I cannot "go back". Have any of you gone through a similar experience or have advice on navigating this transition?

Edit: To clarify, I'm interested in hearing how others have made a significant career change beyond just getting a new job. I am incredibly fortunate to not have any financial pressure while I work through this and I can take the next ~1 year to really reflect and search. It's the how to get started that I am interested in. I am in my mid thrities.
