Overwhelmed by business success + personal responsibilities

I run a training and consulting business in a niche market. I’m feeling excited and blessed that my business is exploding beyond expectations!!! And I’m feeling some anxiety as to whether I have the capacity (time) to manage the number of clients who want my services. I provide my clients a hybrid format — some classes in person, some virtual. I think I could handle it all…however my husband has Parkinson’s. He no longer drives or is able to help with managing household responsibilities, so much of my time/attention is focused on him — helping him with personal needs, getting him to doctor’s appointments, etc. I have no regrets — and don’t want to have regrets — about my care for him. At the same time, I’m so excited about building this business and want it to fly! Your thoughts, please… Thanks!
