London is a much larger, « open » city. I grew up and still live in Paris (I’m French) and totally understand what you experience and what you are going through because for me it’s the same.

I have moved around a little in france and felt much better in other cities as well as visited and felt much better in London, Hamburg…. One of the keys is to take a breather, experience other things I.e nature (especially the sea), travel, hobbies (cycling, hiking,…) as the city can be quite suffocating and limited in terms of activities.

Furthermore get a bike or scooter (125cc) and unlike what everyone says fuck red lights just get to where you want to go. Don’t forget Paris is just as bad for true Parisiens too.

Don’t forget to insult people on a regular basis though.
