anxiety
"Xanax has been a life saver. I have always had problems feeling a little anxious.  But once I was diagnosed as having a brain tumor at 26, it only made things worse.  My doctor prescribed Lexapro, which worked okay, but I didn't like the way it made me feel, so I stopped taking them on my own.  One particular night about 3 weeks ago, I got so upset that I thought I was having a heart attack.  I was dizzy, chest hurting and pounding, weakness. Nobody could find anything medically wrong with me.  I asked the doctor for something for anxiety to which he prescribed Xanax 0.25mg every 6 hours and within the 30 minutes of taking it, all my symptoms had diminished.  Xanax really saved my life."
