Fluoxetine
"I've been on fluoxetine for 8 years plus for depression, anxiety and obsessive compulsive disorder.  I thought I can do without it so I stopped several times in my 8 years and I can tell you that was a mistake.  I have severe depression and my anxiety goes through the roof and death would be a welcoming concept.  But I know I can't live without the medicines. It makes me think categorize my thoughts and I think more logically without compromise."
