Pros and cons of following your dreams

I got accepted into a program abroad, which has always been my dream, but now that it's actually happening, I'm terrified. Studying overseas sounds exciting but the thought of leaving my family and starting over in a place where I don't know anyone, hustling for money every day makes me wonder if I’m making the biggest mistake of my life. At the same time, I know I’ll regret it if I don’t take this opportunity. Sigh… Has anyone else been in this position? How did you manage? I’d love to know.
