My dear sister Lately, my sister dosen't feel good, she is so depressed, she is always crying and always in the bed, she dosen't want to eat and she dosen't want to go out. :( I don't know how to help her, I don't know what shoud I say to comfort her. I feel like I'm a useless person right now. I'm her old sister so it is my duty to help her but I don't know how, I really don't...
