I've been taking 50mg of sertraline to help cope with my anxiety for the past 4 weeks now (first 4 days on 25mg). Since starting I've continued to feel anxious quite often, possibly even more frequently than before. I've also noticed that I've been feeling down more often - as if life is pointless and hopeless. I didn't really feel that way prior to the medication and so I am concerned it's being caused by the sertraline. Has this been a side effect for anyone else who was previously only experiencing anxiety and not depression? And has it gone away after a few months? It's so difficult not to over think every thought/emotion that I have!
