For the purpose of determining on-topic/off-topic is this question Weighing pros and cons of quitting against other life circumstances fundamentally any different than one asking "what job should I take"?
If I were to rewrite the question down to its simplest form:
Can I quit anyway?
I know that I shouldn't resign before finding another job, but I really don't like my job. Is it okay to leave anyway?
This is looking for confirmation of the asker's beliefs, not for actual constructive advice. As discussed in the help center:
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
This is definitely not practical or answerable.
