Be honest: are you excited to go to work in the morning?
There's no shame in admitting it if you aren't. What it may mean, though, if you are a business owner is that it might be time to call a business broker and discuss whether a sale of your business might be an option. Don't put this off until you are completely burned out. Selling a business can be a multi-year process, where you may want to make changes to the business to make it more marketable and valuable for a couple of years before selling, and then the selling process itself may take 6-12+ months. You might then, depending on the characteristics of your business, need to be involved with a transition for 2 months to 2-3 years.
While this can be a significant undertaking, imagine how it will feel to free up your time and gain liquidity that you can use to pursue something you are passionate about.
For businesses with $2+ million in annual revenue Codiligent business brokers offers a free marketability assessment that can help determine what issues may be inhibiting marketability and value that you may want to address before selling your business.
