you can hang yourself from a kitchen chair if you were desperate enough. a bed sheet, pillow case, shirt, or pair of pants tied to the sink or corner of a bed would do it. but you have to lay there while you choke until the blood flow to your brain is cut off long enough to pass out, allowing you to finish suffocating. It's not an easy instinct to fight, but it's been done.
I don't think epstein did it, by any means. but it's possible to happen.
