This
before doing any of that sit down and do the numbers.
How long can you go without earning?
What are you skills and what else could you get?
If after thinking about it you are ready to quit ask for a meeting with your manager, explain the situation commute etc, job not worth it etc.
If you manage to get your work condensed into 2/3 days, try starting your own business in the other days.
Good luck fella
