I agree with what Jessica said,
But I think that your question can only be answered by you. I did it, I went away, in a country I never was. I would not say that the country changed me;
I was forced to change myself.
What I mean is if you do that, you are going to be alone, no really alone. It doesn't matter if you can write or phone with your family friends at home.
For me what came with loneliness were several things;
But most of it were some serious crises, fear, uncertainty about who I really were and where I was going on a professional level (studies) as well as spiritual level. Some people say that if you ask yourself a question you already have the answer inside of you, but you dont accept it or you fear it. I personally do not think that getting away is like a magical thing and that all your problems are going to be solved without any serious trouble. People always tend to glorify and make it seem easy and painless, it isnt, if you leave a country with personal problems or doubts, they are going to follow you.
Well, I dont say it is all negative, It helped me a lot, opened my mind to new things and other way of seeing life. And one of the benefits of that loneliness it brings is that you have a lot of time for you and to think. Travelling did bring me this because I wanted to, I wanted it to be like that, but it does absolutely not mean that it is going to be the same for you. Some people travel in another country and still go to eat in Mc donalds
So if you feel like you got what it takes to do this journey then do it, leave it all and go, but dont you dear think its going to be easy vacation time sunny and all the people love you thing.
Plus do you speak Italian? because Italians, especially in the south even more in a small town do not speak English
And I you plan to live there
.
I wish you all the best.
