I remember the GP telling me that I may feel worse before I felt better which totally freaked me out because I already felt awful, fortunately I just felt no change rather than getting worse. There are so many other pills to try that will work so please try and not loose heart. I imagine first your GP will want up your dose before trying a different med but because you're not pregnant or breastfeeding you have so many options. I know it's hard to see while you're in the depths of it but you will feel better, I promise. How are you sleeping?
