When I was in the same situation as you are, before my resignation, I told my bosses that I will leave soon and I don't want to receive big projects now and asked to finish all the important stuff I need to finish. Actually leaving the job was the best decision in my life. I had much free time and transformed my hobby into my business. Of course, it took a lot of time, but I had money left after many years of working and it helped me a lot. You can follow the
