I was watching the video of Jay Swanson, who moved to France. I can see many points that can be food for thought for others who want to move to France for various reasons.

His key point is to take some distance from your life and the world around you to re-evaluate, heal, and solve your issues by seeing them from a different perspective.
There are lots of other challenges in moving to a new country. I have personally helped friends in the process of (re-)settling and have seen struggles, despair, and questioning of oneself. I remember a conversation with someone who had it particularly rough leaving England and was consumed by self-doubt. A part of him wanted to return to England, following overwhelming stress and frustrations.

He brutally felt the language barrier: he learned and perfected his French through classical books and felt like a time traveller talking English like Shakespeare trying to open a bank account. The locals told him his French was excellent, but there was a gap between what he said and what he meant. He couldn't have meaningful relationships with locals because of this dissonance. He felt there was no way to make friends until he found a popular activity to join, where he could finally play a local pass time and get to know the locals. This little thing made everything click and changed his life there.
( I will go on and on about Petanque in the South West of France, but that's not the point)
For him, the process was a reconstruction that went through lots of significant challenges. He found himself.
It might not be easy, and you have to expect the challenges. There will be the external ones and the baggage you are carrying with you, but moving out of your comfort zone will create a new space for personal growth.
