I've been diagnosed with pnd and have been taking the ads for a week. I now can't sleep and actually feel significantly worse, I'm angry now as well as exhausted and as flat as I ever was. Before I just felt low, not angry and I still slept well. Now I am shouting at ds (3) and feel like I'm on the edge of losing it. Is it normal to react this way and will it settle down?? Please tell me yes as I'm just not coping (ds2 is teething and currently crying non-stop)!
