"i&#039;ve battled depression for five years and anxiety since i was a kid. the first two weeks on prozac, everything got ten times worse. i couldn&#039;t function or stop crying or hating myself. but after that, the depression subsided. i&#039;m more confident, calm, and i shy from negative thoughts and sadness rather than welcoming those things like i used to. it has helped my depression an incredible amount, but i have seen a little less improvement in the anxiety (even with cognitive behavioral therapy). side effects for me are lots of yawning and loss of appetite."
