Does anyone know if post natal depression can go on for three years? I suffered from it when my second dd was born. Didn't seek medical advice until she was 13 months old as I was certain it was just tiredness and that it would go away. Was prescribed anti-d's but have stopped them now as I felt more in control. I am definitely better than I was but still tend to get very low on occasions and wonder if maybe I should go back to GP again and if medication would help me. I have absolutely no reason to feel down like I do and it annoys me sometimes to feel this way. My poor family are taking the brunt of my moods and I don't like to be this way. Would be interested to hear from anyone else who feels this way.
