You are dying: This is a classic symptom of advanced toxicity from meth. You are going to die very unpleasantly from your habit unless you get help giving it up. Even if you have so little regard for your health to have gotten yourself into this situation, think of the people who love, or used to love you. Let this thought give you the strength and courage to overcome this terrible affliction. Be brave and live.
