Remember the fine balance between Idealism and Pragmatism. Given the current state of the World/Economy, taking unnecessary Risks when you have a Family dependent on you is absolutely not worth it. "Safety First" should be your current motto. Don't listen to rah-rah/gung-ho/YOLO folks and ruin what you have now. The proverb "A bird in the hand is worth two in the bush" is more relevant now than ever.

That said, staying in your current company and trying to move up the Management Ladder will come with its own challenges. Confidence is good but not Recklessness nor Foolhardiness. As others have pointed out it will not be easy but Persistence, Hard-work and some "Smarts" will see you through. "Stick it out", "Don't rock the Boat" and you will be good.

Good Luck!
