I also want to add that I have asked doctors, but the ones I have gone to have not yet been able to explain what has happened to me.
When I was still reading things online to try to get an idea of what was going on, I saw that some liken antidepressant withdrawals to the withdrawals of addictive drugs....In that there seems to be a post-acute, extended period of withdrawal. That first there are the initial physical symptoms of withdrawal, and then what follows are the emotional/psychological symptoms which can last a really long time, like 1-2 years. (And they wave/window during that period, but gradually improve).
However, I have read about people who went through Cymbalta withdrawals but felt pretty much recovered after a number of months. So not all are affected equally, I guess.
