Marriage and children can make one feel trapped. They definitely place limits on one's freedom. Children are expensive. It sounds, however, that you truly love your kids and are devoted to them. I hope they add joy to your life. You sound like you have a lot going for you: a great job, two wonderful children, a wife, a house. I hope you can feel gratitude for what you have. And I hope you can find some relief from your depression. Young children suffer when their parents are depressed.
