Name for anxiety going from employed to self employed?

[Lam N.]

I recently lost my full time job. The thing is we have a business that's already thriving and already replaces my full time salary. So, we decided instead of me trying to find another full time job we should just go all out on our investment business. Aka self employment. 

The thing is we have both been conditioned to feel secured with a full time job. Now that neither one of us has a full time job, I feel really anxious. The math works out. Our rental income is enough now to replace a full time job. We have a lot of cash stashed up. We have the means to get lots and lots more rental properties. And yet we still feel really anxious that neither one of us has a full time job. 

Is there a name for this type of anxiety?
