The Life Of A Depressed Older Sister

The things that I have written are fantasy, though the ideas of depression and older sister syndrome are true, the magical things and murder are NOT real. Please note that I have never murdered anyone and developed magical abilities, also I have never been to war. The story follows an older sister who would do anything for her three siblings but is facing struggles to overcome her trauma, and is therefore sometimes an emotional abuser. She tries her best, but she is just a child herself. She's thirteen. Please remember that as you read the story. I hope you won't hate my main character as much as I hate her.
