What did your nervous breakdown look like?

I’m interested in the physical, mental, and emotional sensations experienced during a nervous breakdown.

I had racing thoughts of suicide that were unshakable, even though I was certain I wouldn’t follow through. Simple daily tasks were insurmountable. My thoughts revolved around the black abyss I’d sunk into. My brain felt like it was on fire at times. It was a literal physical fire.

If you don’t mind, please share.
