Corzlite, these last comments appear counter to your initial post about your desire to experience something new by going away.
These are natural questions, and you should keep them in mind, but they should not stop you from going. Depending on which country to which you'd like to go, some time with online searching should net you various expat websites and blogs which should help address your questions. For example, while based and centred very much on München,
Toytown Germany is an interesting place to start for Germany.
If you're going to a country where English is not the primary language, spend some time learning some of the language before you go; pick up standard words and phrases. No one expects you to be fully conversant, but the people
will appreciate your effort in trying. My first conversation with my landlord/landlady was very entertaining, and there were genuine smiles all around.
As for the USD-EUR exchange, politics and foreign policy are a bitch. It hurts, but there is little you can do about it on your own.
So, go!
