Many won't be able to make it. Remember the scene from the movie The Road, where the guy's wife just gives up and walks out at night to die. That's how most city dwelling females will cope with it.
If you're up for independent living/homesteading like a mountain man of old, you can make it and thrive. Imagine, no more society, no more rules, no more regulations, much lower human population and thus competition after the first year if you can make it to that point.
Nobility by the sword. Become the hero you've always wanted to be.
