I think you can probably afford some other avenues before you turn to "pharmaceutical aids".
I'd suggest you talk to somebody about it. Family, an independent business advisor, take on a staff, or even split the business with a partner for direction. Just put yourself in a situation where you can get an opinion back on your ideas.
But sure, if anxiety isn't new to you, there's no shame in talking to a doctor about it. It just wouldn't be my first suggestion. A good doctor should push you towards CBT anyway.
