It's extremely common to feel this way, Amigo. Keep your chin up and remember, all that stuff going on inside of you is just that, inside of YOU. The world around you is full of opportunities and other people who walked a similar path, or perhaps a completely different one. It's a fact that the one thing you will have in common with them is the basic need to connect. Perhaps making a few connections with your surroudings will help you feel a bit more grounded in your decision to travel.
In the words of Frank the Tank, "Just keep on truckin."
