I recommend you to read the book "Sedated" by James Davies. It explains how being medicated for depression for long periods of times makes you progressively more depressed. Symptoms become more severe and medication becomes progressively less effective. All the studios that the book points out show that depressed people not medicated progress better, but the ones medicated for long periods develop chronic depression.
I'm not saying you should stop medicating (you never do that by your own), but at least you could read the book and ask your therapist.
I suffered depression, tried to commit suicide and took medication, but even if it helped me at the begging I never liked how it changed my personality. What I did was to read a lot of books to understand what is depression and why occurs, to progressively stop taking medication. Now it has been for years without medication and I feel better. Don't get me wrong, I don't feel happy, I almost never I managed to feel happy, but I'm not depressed also, I'm simply stable.
I wanted to know more about depression because my mother suffered from chronic depression, also my old brother. Both started to took medication and took it until death and they NEVER healed. I simply don't want to end like them.
