When I resigned from my 1st job to start freelancing, I was like: "If I do it for 6 months, I will be happy. If it goes wrong, I will become a normal employee again". It was 5 years ago.

Don't be afraid, do it!

I took 6 months to make my decision. I already had a family, millions of projects, etc. No one can make this decision for you. If that's what you want to do, you have to do it.

Is it complicated? Damn, yes!
Is ok to be afraid? Totally
Is it worth it? 100% yes!

I still have no idea what the future will be. If I will be able to be a "normal employee" again. I just enjoy the journey, meeting new people, travelling all over the world, work on awesome projects with cool people.

One day, it might stop but who cares? Enjoy your luck!

Stop be afraid of what could / will happen. Put this fear somewhere and live with it. Enjoy today. Spend some time with your family. Work on what you like. Life is too short
