Yes, ThisWayOut, I think many if not most individuals who struggle with major depression have had this experience at one time or another. I know I have. In fact, I was kind-of in that sort of place yesterday. For the most part, I've been doing rather well recently. But yesterday, for some reason, I sensed there was a dark fog trying to settle in around me.

The thing is, over time, I've learned to pay attention to what's going on within my psyche & to question why things such as this dark fog are occurring. So when something like this happens if I ask myself why it's occurring, & the answer comes back: "no particular reason" then I know it's just my old nemesis "depression" flexing its muscles. Realizing that seems to dissipate much of it's power.

I hope that you can also find a way of draining the power out of your crash so that you can turn it instead into a soft landing.
