I would say acceptance on some level that we are living in very anxious times, can help.
It is not all you. Is what I would like to say.
Having said this, putting things in place that help, for example eating the right foods (to combat anxiety), and all the things i.e. exercise that help too.
With anxiety and depression though, sometimes these things are difficult to do. And I know it is important to realise that.
These days I try to reframe my anxiety as a positive force, instead of hating it.
If I'm worried about something, as far as I can, I try to look it in the face and tackle it. Example, you worry about finances, then check your bank account everyday, get yourself a notebook to write down what would help, tick it off get on moneysaving websites etc.
Try to see it as a challenge.
You worry about health, Covid etc. So control what you can control. Choice of foods, drinking enough water, attending your appointments including the dentist etc.
That way at the end of the day you know you have done what you can. And hopefully you will have a pleasant living environment to sit and rest in when you need to.
Be careful about t.v. I check the news online once a day only.
To stay informed, understand the risks if there are any, but try to be aware that some of it is fake news and can be disregarded. It does have an affect on people hearing it blaring on the background all the time.
Whereas with books, paper news and a website you have more choice about what it is you are exposed to.
