My coping box has the entire set of the Harry Potter movies. 

I shared on a new thread - that I called The Toolkit about the psychological tools I use to help myself, and manage my various conditons arising. @Former-Member suggested I replicate that post here in this fantastic thread "Coping Box" post started by @Crazy_Bug_Lady.

I have not brought across the whole post which had some autobiographical content about my Bi Polar (have a read if you like at The Toolkit )

So here's the tool...

THE SILVER DIAL

One thing I use is if I feel I am ramping up into hypomania or sliding terribly into melancholia is THE SILVER DIAL. 
I imagine a big silver dial with High, Medium, Low and Off on it and I imagine in my mind's eye turning it (and thus my mood/emotion/energy level) down (or up) to midway 'Medium". I also use it too when in the PTSD moments of flashbacks, or intruding suicidal thoughts - I grab that dial (in my mind's eye) and turn it to OFF.

I am always looking out for new helpful methods, so would appreciate any sharing of things others do to help themselves that I could pack into my toolkit for future use.
