Lamed Vavnik, in switching your job, I wish you all of my blessings. Though every life decision involves risk, it is only when we are willing to take the risks of our decisions that we find opportunity. With trust in Hashem I'm certain that He will guide you toward the right decision. I don't doubt that.
Your focusing on your strengths as well as the positive things in your life, as you are doing, is a great way to overcome this struggle you are having with the y"h. The y"h who feeds off of our sense of emptiness and lacking won't have a shot at you.
Keep up the great work, stride after stride! From 20 onward!
