Asked these two questions to a couple of people that now live in London to get a bit of insight into dealing with city stress in a large area.

How or what do you do to escape from the busy stressful life of the city without actually leaving it?
What do you do to make new connections and/or feel less isolated within the city?

Melissa:I moved from a town of 35,000 in New Zealand to London. Its crazy. To escape the stress I drink wine and visit parks as they're relaxing still jam packed but having nature around me is always nice. I'm also a shift worker so sometimes I'm in central at 2am where its a bit quieter.
To feel less isolated in London I'm on a few pages on Fb to help meet people/get advice. Tinder also helped(its for everything here. I used it to find friends). Tbh Ive never felt isolated in London. I always have internet(unless I'm on the tube) so always connected to people. I hope this has helped? Lemme know if you want me to go into more detail

Megan:
London definitely is overwhelming. I like taking time out in the parks (yes the popular ones are crowded but smaller lesser known parks are great), I also like to excercise in the outdoors. Anything outdoors is great. You need to get away from buildings and technology and the rat race. I also book holidays every 6-8 weeks just so I have something to look forward to and something that makes working so hard seem worthwhile.
