There is no way to choose a date, at all. A person needs a trigger. When they have such trigger, its when they do it. Otherwise, SI is very hard to overcome, some may do it, but the general way is that something happens or triggers an emotional unbearable reaction that one just does it. I have been having those triggers but i have people that live with me so i dont act up. If i lived alone those triggers would have killed me and i would have been free from this place
