I have a business, my anxiety mind goes what if my business doesnt go well and i have to close it. 

What if your business doesnt work, so i had to make a plan b. That is to learn a skill. If i lose my business then i will use my skill to monetize and earn or get a job. 

So i decided to be an illustrator.

Now my thought is, there so many jobs already people are doing in it. Its saturated. You wont get a job, plus you know nothing about illustration. You barely have drawing skill and to reach at level of perfectism it will take you 5-6 years. And what if you dont get a job.

I am making so many backup plans because of anxiety. What if this - what if that. 

Do YOU also suffer from this? What exactly is it and how do you cope?
