Anxiety is something I struggle with.

I'm an older person. And it seems like the older I get the worse my anxiety gets.

I don't see a therapist nor am I on any kind of medication... for anxiety or anything else for that matter.
Things that help me to keep my anxiety level down include keeping myself occupied... mostly doing household chores (I'm retired & I'm also pretty reclusive. So I have a lot of time on my hands.) I also do about an hour-&-a-half of mindfulness yoga most days. And I have a small dog I take for walks a couple of times a day regardless of the weather. (We live in a townhome & have no yard. So daily walks are imperative.) I also spend quite a bit of time here on PC.

All of these things put together help me to keep my level of anxiety down to a dull roar, as they used to say.
One other thing I'll just mention is that, personally, I feel it's important to maintain a peaceful, calm environment. I avoid watching any kind of violent TV or movies. I don't watch the news on TV. And when I listen to music, it's mostly of the quiet, calming variety.
