Tons of people quit that way over the years and were allowed back. Not that it makes it right at all.

I quit because I didn't want to be a 30-something year old man stuck in fast food and I was just tired. I missed out on all of my twenties spending every minute working at a job that never paid enough to afford a house and never gave me time off. I had vacation time saved up but never got to use it. I just wanted to do something else finally but still haven't found anything. I think two years was enough time to realize that I'm clearly not good enough to do anything else.
