And.... I need to take heed to my own words of wisdom and advice on here. I tried to give as many positives as possible to my CEO when I gave my notice, coupled with some honest feedback about the high turnover in my department, the lack of leadership within my dept, and the large workload that led to burnout. If he cannot take that feedback maturely and respond in a mature manner to that, then it's HIS problem, NOT mine.

I need to adopt a healthy mentality about this. He is indeed toxic, and he has proven that to me several times over with his behavior and responses. And, I don't need to participate in the negative, toxic drama, since that's what he wants to create here, as I am leaving.
