There certainly are. Never fear.

You could say fuck it, grab some cheap food supplies to last you a bit (Sell all that junk you won't need if you're really desperate. Can't bury you with it) and some seeds and go find some natural place where you can live off the land. Throw some seeds down and if you ever feel like you have no place to go...

Go there. Have trust. Have faith. It's better than nothing.

It costs you ten bucks for a huge bag of white rice that will last you for ages. Asian people live so long partly due to eating white rice y'know. (brown rots due to oils) and ten bucks for seeds.

What have YOU wasted twenty bucks on?

Plan ahead, and include your family. Make it a game rather than a chore. Together you can survive anything!
