One of my friends moved to the city to follow her dreams. I'm so jealous of her.
Why are you jealous of her?
Because I want to follow my dream too but I'm scared.
I know you are jealous of your friend's courage to follow her dream, but you shouldn't be jealous of her success. Use her success as a motivation for your own success. Take steps to achieve your dreams.
I think I should go to the same city and live with her. I love her.
Has she asked you to move in? It's good to want to make your dreams happen but I'm not sure you should invite yourself into her apartment no matter how good of a friend she is.
