Depends on what you are worrying about. Is it your product's future? Competitors? Keeping customers? Managing employees' performance? In my experience, stress comes from having all of these problems but not having any plan. I would write out everything that is stressing you out then try to find the highest priority. That feeling of having too much to do is a GOOD thing. It means you have tons of ideas or your customers love your product and want to improve it. That should never go away if you do your job correctly. You just need to develop strategies to know when your roadmap is full and how to manage scope/expectations. Maybe you need a Product Manager or Salesperson to handle expectations from your customers?
