That is perfectly normal and really just fine.

Creating a company, growing a company and maintaining a company are three different jobs and the best fit is rarely the same person.

Now that your creation has matured, it may be time for you to hand it over to someone else who will protect your investment while you find new areas of personal growth, such as another startup for example.

You probably need to find yourself an operational successor you'll be happy with, gradually hand over your responsibilities until your level of involvement matches your interest - in your case that would probably be board member / adviser only - and enjoy being a shareholder of a valuable company.
