Hi Laure,
If you have a story inside you trying to get out I believe you need to put it on paper regardless of whether or not another person will read it or like it. This has obviously got strong meaning for you and may be a way for you to grow as a person through your storytelling. Sometimes it can be difficult to keep going with something that seems so large but I find that spending even 15 minutes a day on my projects can be enough to get the ball rolling and before you know it your novel will be half finished. Good luck.
