'Sticky thinking' hampers decisions in depression

Being an engineer, I use the analogy of SNR, signal to noise ratio. Depression and anxiety, often comorbid, raise the noise floor to the point that it is incredibly hard to feel confident that a decision can be made. This in turn results in a decision NOT being made and progress dragging on... which only raises the tension around the situation. It is a horribly vicious downward cycle.

I have seen this first hand in loved ones and also experienced it occasionally myself, though thankfully less frequently. I am extremely adept at compartmentalizing, including work and life... but a deep depression knows no limits easily bleeds over into everything. The mental noise is deafening. I was shocked how strong the effect was during a recent episode of depression, despite my typically strong executive functioning skills.

Equally amazing is the 'blue skies' and 'quiet mind' that can be achieved with proper treatment, for which I am infinitely grateful.

Please seek out help if you are struggling.

If you wrote a book called "Mental Health for Engineers" I'd read it. You are very good at articulating the subjective experience.
