Go for it Vallie. I swear you will regret it so much if you don't. I am so glad I did and there are so many more benefits from doing this then you have listed.
I remember we got a scholarship for our first year, that you can apply for, something European anyway that everyone can get. Money should not be the reason why you don't go, I know it's the practical one, but it really would be a shame.
Do it! You will not regret it. You're only young once and this is the chance of a lifetime.
