Ok, this is the thumb thing.
Let me tell you when you absolutely need to do the thumb thing.
When someone is having a panic/anxiety attack, do this.
Don’t crowd them or hug them, unless they specifically ask you to.
Do this, and try to make eye contact with them.
Tell them to focus on your thumb. Maybe draw little shapes.
Don’t say “calm down” or ask why their panicking, just try to get them focused on something else.
This small, intimate, gesture will 9/10 times distract them enough to not be so overwhelmed with negative thoughts.
