It sounds like you have already had a day to re-think your decision to move away to
unknown spaces. GOOD. Don't imagine an overly romantic idea of travelling thru
Europe, living out of your backpack. It would be more like a homeless person's
journey than a romantic adventure. The average illegal alien in USA has family and
friends to help him. He can obtain papers or live on cash under the table, because
people are helping him.
You can only live on the cash in your pocket if you stay where family or friends are
around. Moving off to be by yourself, you will sleep in the park or under a porch. You
will be so dirty that people won't offer you a small day's wages for your honest work.
Even the worst situation where you have to live with family allows you to get a decent
shower everyday. Family is supposed to help each other. Allow yours to help you, and
you can return the favor years from now, when you are slightly better off or even much
better off.
