Blaze of Glory
I haven't given the main character in the story a name because I couldn't think of one that would be suitable. Perhaps you, the reader, can.
She had a fascination about death and decided that she would explore the best way to die so that she could dictate how her own funeral should be.
She used to self-harm to punish herself although she didn't know why she did it, she just went along with the compulsion.
She became an actress, loved by thousands, but then they never really knew of her dark side, they only saw what she wanted them to see.
