This is not meant to Be an insult. I was in the same position about 10 years ago. I had been at the same company for nine years.

I found that my skill set wasn't what the market wanted. Sure I had been successful in my projects doing basically the same thing for nine years but I had become an expert beginner (https://daedtech.com/how-developers-stop-learning-rise-of-th...)

I learned my lesson. I took a job after working for 12 years as what for all intents and purposes was a junior developer (making a little bit more because wage stagnation is real). I've had 5 jobs since then and kept learning.
