When I was younger, all the detox staff would say "nobody ever died from not sleeping". They would happily let you stay up all night, night after night. I was lucky to be in a place during my second detox, where they went against the rules and let me sit in the tub for hours at a time. Of course now the medical community understands how absolutely essential sleep is to your body and mind. I believe that the lack of sleep compounds the fundamental issues that create the impulse to "get high" to begin with. So then you are left with your originally fucked up mental/emotional process...and now you can't sleep! It's a long and winding road, and the older and more experienced you become at feeling like shit, the more hopeless you become about your future. Happiness is a naturally occurring drug. Unfortunately it's one that you are either born with the capacity for...or you are not. Getting older will not make anything easier. It will just give you more shit to reflect on. If you can manage to rid yourself of the mental crutch that drugs can supply, then I guess it's best to do this at a young age. I wish I could give you more hope, but I have never been good at finding it. I can definitely tell you that you have to sleep. Try the hot water tub for as long as possible, drink some hot milk and go directly to bed. Get yourself one of those noise machines and try the white noise. Sometimes that will help to shut off your thought process a little. I am thinking of you and hoping you can get to a better place.
