I have had the same experience. The environment was toxic, I was actively interviewing, and the company knew I was not happy. I was preparing the give my resignation the next day, as it turned out, but they pulled the trigger first. Regardless, like you, I wanted to leave on my own terms. But keep things in perspective. Put shame to the side because that's not going to help. If you are a frontend developer, there is no shortage of job opportunities for you. Keep going with the interviewing process, and move on. Best of luck!
