Quit my job

I sent a resignation letter to my employer to pursue full-time coaching or find a job related to training/consulting.
I don’t have any income besides my full-time job but I left it because I wanted a break and more time to pursue something new.

Although I am so scared about my decision, I am also scared about not having income to support myself if I quit my job. I feel like I can get a job and create the opportunity but some part of me is hella scared about what if I don’t find a new job or make money.

I feel kind of foolish because I turned down the job that was secure for me. Also the situation with corona makes it harder to find a new job.

Yet some part of me does believe that I can easily do it.
