Going to school abroad
I think it depends on your personality as to whether or not you'll feel isolated. Have you ever had to move to a new place where you live?? Did you make friends easily or was it rather difficult?? If you're the type of person that tends to have no problem conversing with others you should find moving to a country not too much of a problem. I would advise you however to try and at least study the language you will be moving to if you don't speak it already. For one, even if classes are taught in English I'm sure you'll encounter patients later on in your training that will want to speak their own language (I'm mean think about it. Would you want to have to try and speak in a foreign language when you're in your own country and sick just because the doctor can't speak the mother tongue? I know I wouldn't). Just my two cents though.
