Re: Sertraline is making me "numb" and indifferent.
This is a difficult question because it involves trial and error and the dreaded Medi-go-round. I was on Sert for nearly 5 years and felt "apathetic" and flat too. In the end, it stopped working for my depression.
I don't know whether you have tried augmenting Sert with Mirtazapine, which can sometimes work, or trying a completely different class of AD. I switched to Venlafaxine, which has helped with the apathy - but only moderately.
And this is the core problem: Most meds come with the problematic issue of side effects, so it's a matter of weighing up the pros and cons for you as an individual.
