generalized anxiety disorde
"I was always someone with underlining anxiety about anything. Stupid things like where is the bathroom or how hot will the airplane be. I hated flying, be passenger in cars but even with all these silly things, I never had any physical symptoms. 

No one know what anxiety is unless you experience the debilitating physical symptoms of it. I was an absolute mess. Was put on Celexa 10mg right away and it simply was way too much to jump on. I stopped after 4 days and freaked out thinking I was going out of my mind. 
Then I reluctantly started Lexapro after seeing my first Psych. He started me on 2.5mg and went up to 10 within 6 weeks. Finally a year later and total CURE! No more anxiety. You'll love this medicine."
