my exam and my friend

I am going to take a very important exam and after that I am going to visit one of my best friends. Meeting her means a lot to me now, since I feel she is the only robe that connects me to my past back in my homeland. I don't know how to put it into words; I feel like I am going to experience a sweet part of my memories. However, I feel a little bit worried due to my exam. Please wish me luck
