Travelling alone can be depressing. Don't just run from your current lifestyle, add something to it. Travel with a purpose.
Stuff like 'Homes for humanity' and many other travel related charities can be quite expensive.
But you can travel and work. Not travel and hack, just work.
I'm not sure what is near Atlanta, and what's available. But you already have fairly nice weather.
No matter where you go, $2000 isn't going to get you very far, flights to buenos airies as an example are nearly $1600

Cruise ships could be interesting work if you're into that. I've worked in Ski Resorts for much of my life, and the first few years where you aren't focused on making money or getting ahead, but just looking for an experience were amazing.
I'm a believer in the greatest path to happiness is through service to others. Discovering your purpose is a big part of that. If you don't have a purpose, the best way to find one is to do something, anything.
I hope that helps, though it isn't a direct answer to your question.
