I started on 50mg of sertraline 2 months ago, start my third month tomorrow. For the first 2 weeks I felt like I was in space, very spaced out, headaches, nausea and my eyes were bright red. This has very much eased but now I feel dead inside, I have zero emotion, I'm bothered about things but just feel like I can't feel anything. To go from crying every day to now nothing feels very alien to me. This is concerning me as I want to at least feel human. In terms of my mood, I feel better at least. I'm also struggling with my sex drive & being able to climax now which I've had no issues with previously.
