Most anxiety comes from trying to control things that are outside of your control.
Giving your focus to controlling the controllables while leaving the rest to the sovereign goodness of God is the key.
Because they will not give up the throne.
I don’t see any way around it: 99% of the time I believe it’s a faith issue. Jesus said be anxious for nothing, and I share this message with all empathy. If you don’t have Christ I completely understand why people have anxiety.
