depression
"I'd suffered from anxiety and depression for many, many years. The anxiety led to trouble sleeping, which made me depressed. I was focussing on the negatives in my life and my circle of friends was shrinking. I began to feel worthless. I am a musician but also a software engineer, a job that is secure and pays well but gives me no satisfaction. I took fluoxetine in 2004 when stress at  work brought my  anxiety to a head. I also used Zolpidem to sleep. I kept up this pattern for a couple of years, quitting Prozac and re-starting regularly. In October 2012 my sleep became awful and I was regularly just walking out of work because I couldn't carry on. I started Prozac again, and since then I have been on it. It has transformed my life."
