I feel like this a lot! For me, when I'm in that state, I have to try and stop doing 10 things and just focus on 1 thing. If I'm making dinner, then I'm making dinner. If I'm journallng then I'm journaling. My tendency is to try and do a whole bunch of stuff at once but that winds me up like a spring until I'm ready to snap.

Also, if I'm already having a hard time relaxing then I personally find the TV and the internet too stimulating. I need to turn those things off and have silence if possible. I was reading somewhere - and now I can't remember where - that it's restful for the brain to focus on just one task for a sustained period. Obviously that isn't usually possible, but I do find it helpful when I am able to do it! Meditation is a great way to train your brain to focus on just one thing.....

I think your idea of going out for some fresh air is a really good one. Sorry it's so cold where you are!!!

Sending you peaceful vibes!!
