Answer:
My Dear Friend,
It's wonderful to live in Britain but I want to start a new life a new me. So I want to leave for the big city. I want to leave because I want to see all the place's and things i never saw in my life. It's just i dont want to stay here longer I've seen a lot and that's why I wanna leave Britain. I went to Britian to follow my dreams and become an actress but nothing happend. But in the big city you always have a chance. I also feel super excited because this is my chance to make my dreams come true! I'm so excited to move but I will miss you I'm sorry that I'm going to leave but you'll understand. Bye!
Sincerely,
Your friend
