First of all, hope you realize, it is your courage and conviction that has brought the business to this level. If you question your confidence at times it is because you have a healthy habit of being able to level with your own optimism. There are obvious strengths that you innately have and there are challenges you are dealing with. The strengths that your have are to be leveraged to the optimum to make you and your business a powerhouse of performance. There are a lot of ways in which your concerns around your business can be addressed. It can be done either through professional help or talking it out with your trusted mentors. But, in all this always remember your vision and your hard work has been the real fuel for this business. You have to nurture and grow through the highs and lows. Yes, there will be some lows. But you will weather them if your heart is at the right place, just like how you have been managing now.
