First I want to thank you all for your patience and for some nice and supportive comments I received.
I'm not going to lie to you, times are hard. Real hard. Regarding the project, I still have elements of the book to recover, it is a task that takes time (and it's psychologically heavy). I find myself in a difficult place due to several problems regarding the project and unrelated situations that I'm working on to solve.
Second point, I received some messages insulting me, spreading lies about me and harrassing me and my wife on social media. Please note that I filled two complaints supported by tangible proof, with the French police (as well as American and Australian), for moral harassment following remarks and the adoption of behaviors (call of threads with my former and past employers, threats on social networks, defamation on other projects, etc.) whose only objectives and consequence is to degrade the physical health and psychological balance of my person but especially of my wife and my entourage. I think the two incriminated individuals will easily recognize each other.
If I have been unreachable for several weeks both on social networks and other ways, it is precisely to avoid these attacks. I know it's my fault that the project takes so much time to be delivered to you (as you may know, my computer has been stolen a few months backs and that led to severe complications), but these behaviors are disproportionate, inadmissible and of course severely punished by the law. I myself have clarified and explained my troubles to the competent authorities and Kickstarter.
Have a good day,
