What do you do when you feel restless?

I order pizza and call my mom.

Anxiety here. Storms here.
Just got a pet recently, but she isn’t allowed to be here. The mouse problem got outta control. She ended the matter in one week’s time. Good girl!
The thunder made her so scared she crawled into her carrier and wouldn’t come back out for quite a while after the storm was over.
My life has more issues than Sports Illustrated right now.

It used to be when I had a lot bothering me, I would keep busy. Now I am mobility compromised, and I tire very rapidly.
I double checked my backup light supply in case we lost power. That helped me feel I was doing something productive. After that, I mostly listened to the rain stupefied that it was coming down so hard for so long.
The thunder was quite busy for a while, and lots of it very close. I was sitting right by my big plate window when one went off close by, and practically filled my full view out the window. It was pink and red, and looked quite a bit like a fireworks burst.
I let out a loud yelp.
I let myself feel like the sky was juggling my worries for me, and when the noise stopped I would be allowed to feel relief.
It kind of worked, for right now anyway.
Now kitty keeps looking out the window, you know, to make sure the world is still there.
I guess that is a good thing for us all to remember. No matter how much we worry, when we look out the window, the world is still there.

I go for a walk or, if the weather is good, I go off on my bicycle

I have this (and I tell myself) “I don’t care” personality. It really works when I know there’s something out of my control and I refuse to be affected by it.

It depends. Thinking too much is the central part of anxiety. Just do something you do not have to think about the thing annoying you these days, like my mom pretending to be restless because I do not have a boyfriend.
If it’s a day-off and the weather is great outside, I would go out, have a nice meal, do some groceries, go to the gym, cook at home then, have a nice shower at the end of the day.

I work on a project that requires just enough thought to distract me. Sewing, cooking, stuff like that. Just enough rote physical to keeping moving (that’s why reading doesn’t work for me)

I count my blessings. I listen to rain or crickets or trains on my headphones. I make lists of things I need to do. I think of things I could do for other folks who would benefit from some assistance (who in my world needs some cookies, or some errands run, or some babysitting?). I go on a walk in a scenic area. I plan a trip with friends. I go on Amazon and start my Xmas shopping way in advance. I pull out my paints and pencils and make some art works. I write restaurant reviews for places I love. I take photographs, and organize photographs.

In other words, I do things that need to be done that are also useful to other people, and I work in activities that are fun/and or peaceful.
