One strategy I use to stay calm during the day is.....

Music

I wait until the storm is over.

Colour breathing

make myself busy and be productive

Sometimes, I feel anxiety rising fast. I have to stop whatever I'm doing-take 2 minutes for myself and just do the deep breathing-in while count to 5, exhale count to 5. When I exhale I imagine stress/anxiety leaves my body.

I draw to stay calm. Especially aesthetics. I love art

Walking

Walk

Breathing exercises help

Prayer

Facing fears rather than hiding from them seems to help me.

Accept what I cannot control
