For me - pick a couple of small things that are guaranteed to help you (like basics - home cooked dinner, morning sunshine, decent bedtime - what is super simple but feels delightful?). Anchor to them. You won't do everything but if there's something you can come back to as a reset it helps. Get outside and moving (running is good, even walking, or just putt your feet on grass every day and breathe for a minute.). Make some of these little spaces to feel your feelings, or just to hook into the bigger natural world.

For me its sleep and nature. I try to go for a walk every day (even a few houses and back). I stick my head out the window at night and look at the sky / clouds. Every morning I get up round 6am or earlier. Even if I just wash my face, look out the window, have a glass of water and then go back to bed. Its a little anchor.

And have a list of friends - if you've gone a few days without good easy connections, txt someone a meme, give them a call, organise a walk on the weekend. It hard but it really helps.

Running. Only real cost is shoes. Obviously other exercise too, but running you can do straight from your front door, no travel to work into the schedule, no memberships etc

What are your particular concerns?
