anxiety
"I'm 19 and have suffered with anxiety for three years or so. Previously had been on Prozac and Lexapro which were both hellish. Began taking Effexor XR two months ago and started feeling better two weeks through but out of no where the medication not only ceased to work but actually made my anxiety a lot worse. Have horrible agitation, depression, irritability and insomnia. Pity I could really do with an antidepressant than works!"
