@janedoe2 Personally I've found adhering to some key activities to be key in managing anxiety.
The first is socialising even when you don't want to. Humans are meant to be around eachother and as the world becomes more individualised, tech based, office setting etc. there is less room for natural human interaction but rather a required dedication to social interaction. I know I need to be around other people frequently to get outside my head lest I get trapped in there all day.
Second is exercise in any form. Walking, sprinting, dancing, punching, whatever you enjoy.
Thirdly, hobbies. I feel like anxiety is potentiated by boredom. They might seem at different ends of the spectrum but personally I believe they're highly interconnected. If you don't have active interests then you're bound to ruminate on anything and everything.
Fourth, all that stuff regarding mindfulness that take practice and patience but have such massive payouts when you begin to understand and practice them. E.g. yoga, meditation, active breathing, spending more time in nature, away from the city.
Fifth, substances. Caffeine, nicotine, booze, drugs, they're all bound to have an obvious impact on your mental state but by eliminating them as much as possible your adrenal gland will thank you.
Hope this helped some,
Pat.
