Kinda bummer. This is from personal perspective and I'm really bad at describing internal workings.

Absolutely constantly dreaming of deepthroating a double barrel or finding other creative ways that might be harmful. Being really sad or down or almost starting to cry rather easily.

The odd slow motion or kinda dulled sensations, kinda like being underwater, every movement requires actual effort and focusing, the body no longer moves unconsciously.

Negative spiraling, negative thought patterns being completely out of control and almost constant.

Absolutely everything being boring, absolutely nothing that can engage the brain and keep it focused there.

Not that i am depressed anymore. Been depressed probably multiple times in my life, somewhere in teenage years and in adulthood, but the most memorable one was few years ago after quitting alcohol, probably lasted roughly half a year or more.
