So I'm in the very early stages of planning a novel that deals with PTSD and healing. My protagonist is suffering from posttruamatic stress disorder after working as a nurse in WW1 and receiving the news that her parents are dead (influenza). She returns home and we see how the very noticeable effects of the PTSD are harming her. She wants to forget everything, so badly. She feels suicidal at times too. During all of this she does something very bad (I haven't decided on exactly what yet) but it destroys a very old agreement between her ancestors and the fae folk. And of course they are mad, bring her forward for her crimes and set a spell on her. Basically she forgets everything and becomes a slave. And although she still feels the effect of the PTSD, with the help of others and finding her own inner strength, trying to find a positive outlook she eventually starts to overcome it. And when she realizes who she once was, she knows that it wasn't forgetting everything that helped her. I won't reveal anymore but it is basically a journey of self healing (through a fantasy/historical fiction lens). Would it be too cliche to use this plot device? I haven't really thought that much about it but I quite like how it ties into her journey of self healing and realization. Do you think it works? If not, do you have some suggestions for where I can take the story (instead of using the device)? Note: I should clarify that she will be completely convinced of her new identity, and along her journey she will find clues and eventually the truth will come out. Thanks.
