"WARNING! I received two injections, and it was the worst 6 months of my life. This should come with EXPLICIT warnings, but didn't.  I came down with severe anxiety and depression.  My life fell apart and I had to leave town to regroup.  My interpersonal relationships unravelled. I was so depressed I couldn't move.  I saw a pyschiatrist and he suggested that the depression could very well have been due to the depo shot - he's seen it affect others like this as well.  Also, I rapidly gained 15-20 lbs.  It's been 8 months since my last injection and I am ECSTATIC to report my period finally came back. It can take that long to leave the system! This is a dangerous drug. Monitor your mental health closely. In fact don't do it"
