I'm thinking of quitting my serving job but I still don't feel free or happy
Why would you want to quit?
I have been working at the same job for many years and I haven't paid much attention to my real interests or passions.
It's understandable that you would want to quit a job that you don't like. No job is worth your happiness.
I have bills to pay and I don't have enough money to risk quitting
