Evey, I'm pretty sure that a lot of people warned you about tolerance and the compulsive nature of stims. Day one you can take this much, next day you may need a bit more to get the same effect, then you don't want the crash so you take a bit more, and more, and more. None of us who care about you will take any comfort or enjoy any misfortune that comes from this.
Have a sleep, if you can't sleep then Eat something, try fruit as normally easier to eat - then take a break from the site, put some music on and have a lie down in a dark room and just drift about in your thoughts. A couple of drinks 'may' take the edge off your experience but please be careful mixing alcohol with stims as they have a very strange effect (do not try and get drunk).
