Thoughts, in general, are like the light from the stars that always shine the same brightness throughout the day.
They are always there
Existing, even when you can’t see them. At least that’s how it is for normal people, you get the grace of day to nullify the shining of the light from the stars at times when it can be overbearing.
You get a break
If I could describe what it’s like to have ADHD, picture your mind never turning off. It is always bright for me, and there is no dawn or day to alleviate my eyes from the galaxy of lights I permanently see.
