Hi!
I have an idea of what you’re going through. I went through college with a similar feeling of being trapped. Once I graduated I worked a series of temp jobs saving everything and would travel in between. As for what you should do, obviously only you can decide. However, check out matadornetwork.com they with pay very small amounts to freelance writers if they decide to publish a peice on their site. They also have some pretty fantastic info on traveling on the cheap and what places are safer than others. My personal recommendation is Iceland. It’s very safe, hitch hiking is easy, and it’s beauiful. It is not the cheapest destination but can be done on a budget.
Listen to your gut and don’t force yourself down a path, things have a tendency to work themselves out.
Good luck!
