"i started this medication because i have struggled with depression, anxiety, and panic attacks.  i have been put on random depression meds since i was 14 years old and am now 24.  i&#039;ve tried lexapro, welbutrin, and a bunch of other stuff.  i never really saw improvement as a teenager on these drugs, but it could have been my hormones at the time.  i tried prosac at 23 years old and it seemed to make a real difference for me.  i think i started to feel the difference within the first week, but that might have been a placebo affect.  after at least 2-3 weeks is when i think it really started to work and i could feel a difference.  my anxiety levels started to drop pretty drastically and i was no longer afraid of things like the dark."
