After I had just watched the 358/2 Days cinematic on Kingdom Hearts I.5+II.5 for the PlayStation 4 after not playing the game since 2013, I wanted to watch it just to unlock the gorgeous theme for my PlayStation 4. Upon further investigation, I have come to the conclusion that 358/2 Days is deeper than we all thought. In the beginning, Xion first appears in Day 7. Xion is hooded up, starting the beginning of her depression. The Organization XIII represents her friendships. She has cut ties with most of her friends, except for the ones she cares about (Roxas and Axel). Xion doesn't even talk with them that much, up until Day 24 at least. Here, she begins to talk, as if she were to confess about her depression to her best friend, Roxas. Xion chokes up a little bit, as she doesn't want to frighten him. If you notice during scenes, Xion gets herself into dangerous situations, as if she were to kill herself, but doesn't want anyone to know about her depression. During Day 74, Xion appears with and without a hood in several shots. When her hood is up, it is her depression taking over her, but when the hood is down, it is her overcoming her depression. When Xion can't use her Keyblade, it is representing her being too depressed to do anything significant. When the Organization wants to get rid of her (calling her puppet, "Poppet", etc.), that is a representation of her cutting ties with her friends. Between Days 174-193, Xion is asleep, representing her deep depression. When Roxas is told in the end that Xion has to be killed in order for Roxas to be him again, it is symbolic of her having to cut ties with Roxas, almost as if it were suicide. She doesn't mind being killed off, as she sees herself as insignificant. During Day 357, Xion commits suicide. sorry if this theory is weak, but I felt this was interesting during my viewing of 358/2 Days.
