This is NOT something that you have to do!
How has it gone before, when you put yourself in a situation where you were afraid that you would have separation anxiety? For instance, were you afraid to go to sleep away camp, but then did very well there? Were you afraid to move away to college, but then did very well? If that was the case in the past, I’m sure you’ll do fine.
But if that’s NOT the case, if you crashed and burned in the past when you tried to go away, then I don’t think that you should go. Better to challenge yourself by living at college and resisting going home, than going abroad where you just don’t have the option.
