My company used to have great employees, who I learned a lot from and to this day respect. I've been there 9 years now. At the first sign of trouble, the brightest left. At the next sign of trouble, the next brightest left, and so on and so forth. I don't necessarily think of myself as not bright, but being remote it was a great job compared to my city. Each iteration of trouble I watched the people I respect leave, and those I didn't latch on for power. Now it's in a freefall... I've had 5 managers in the last year, we were bought by PE, and my team was replaced with a new team who are quite honestly the least talented people I've ever worked with. I've never felt less productive, and moreso like I absolutely don't care about the product, and it's very depressing to me. I don't hide my identity online, and don't care that they inevitably see this message.
Definitely find a new job. Take the courage to face the uncertainty. That's what I did, and I'm happier than before.
Think of it is as the mental equivalent of all those physically risky activities people do (mountain climbing, etc.). It can actually be quite exciting.
