I am so sorry to hear about that, but I'm a firm believer in things happen for a reason so as you said, you can look at this as an opportunity to let your business grow.
And that's the beauty of working for yourself. Yes, it can be a little scary at first but the rewards of setting your own hours, not having to answer to anyone, loving what you do everyday is priceless.
You'll be just fine. I think it's all going to work out in the end.
