I forgot to lock my room and they heard the falling
I know there's a chance maybe you did this 'on impulse', without being in a state of mind to think everything through. In the rush of the moment. It's understandable, otherwise most people wouldn't be able to go.
I'm not judging, I don't mean to come off criticizing, really, especially with knowing you're in a horrible, even worse state now then before.
I do feel the need to say, alongside the hand reached saying sorry it had to get so messed up, that doing it this way, at home with people, or people who just might arrive, and not 100% certain you have 30 minutes with no one around, no one at all - is an awful recipe for all those terrible cases you hear about, of life in prison - a 'vegetable' beyond control to free yourself, best case brain dead and unaware.
If it wasn't your bed not holding you it might've been the sounds of your body fighting for air that would alarm people around. I don't think a locked wooden door would've made a difference for them not breaking it to save you. In that case, you could've been another case we read about, a living tragedy.
Again. I don't mean to be a judgmental asshole, I may not be phrasing myself in the best way and most sensitively. Maybe I come off harsh, but I feel I must stress this critical point, maybe for someone else too who might be reading. Hanging, after loosing consciousness, is a 100% done deal if done correctly - with a good rope that will hold, a firm base, and no one around to try and help you too early. Otherwise, not having this in mind at the moment, many do succeed, many or most probably do it on impulse and in a sense they're actually very lucky to have that 'now!' trigger and not think it too much to get stuck. However, it opens the door too wide for bad luck to creep in.
(Again, I'm not just judging but it might come off that way - I'm sorry. Whether it was an act of the moment or what I see as unintended recklessness - I'm not in your shoes, only saying what I think must be said, along with sympathy for how miserable you feel at the moment).
