Writing and connecting to intangible like "fear' can be very therapeutic and reveal logical action steps you can take.
Instead of focussing on the fear of not having enough money which is a scarcity mindset
Try immediately writing all the things that you hand right now with the money you have
Paying electric bill
Being able to afford a meal
Unexpectedly getting something free

Also ask empowering questions like
How can you integrate your excellent writing skill and current childcare business and make money?
Approach baby care companies and write blog post for them
Sign up in fiver or Upwork and start doing projects.
All events are temporary. This too shall pass.
Best of luck.
