There's a lot of world out there beyond Europe. For the vast majority of it, $500 goes a long way.
Try to keep in mind that there are lots of things that are possible that you don't yet know how to do. It sounds like you're just now learning that you can travel cheaply on the road (from people who have actually done so, no foolin'). Rather than accuse us of lying to you, you might be better served taking some of it on board.
Then book a flight out here. I'll use 1/1000th of my monthly budget to buy you a beer!
