One thing I like about turtles is their shell.
When in danger or scared they can hide themselves in it.
As a sensitive introvert I sometimes feel frazzled and overwhelmed. What usually works best at such moments is my way of hiding in my shell. To find a time and a place where I can close out the outside world.
Sometimes this means going somewhere to be alone.
Most of the times it is enough to turn off my phone, close my eyes and be quiet for a longer time.
