I've suffered from 'Acute Anxiety Neurosis' all my life. It's pretty much ran my life, and now i'm borderline insane lol...A psychiatrist once tried to put me on some bullshit drug that "supresses the overactive chemicals" or something like that. But, being creative, i feared it would supress the part of my brain that was creative.
So, fuck em. But i've been taking alternative medicine: St. John's Wort, Ginseng, plus extra vitamin b, and the most powerful (because it can make you fall asleep) is Valerian.
