Hi Ruth - am sure you have looked into this already but have you asked your GP about cognitive behavioural therapy? It really helped my PND, I was diagnosed 4 months ago and am pretty much fully recovered now. Anti depressants also helped me but I don't think I would have recovered properly without the CBT. I have heard CBT is quite hard to get as its very popular but maybe speaking to your health visitor or GP would give them the nudge for a referral?? I too had very very horrible 'flash backs' of a long and difficult birth, the CBT helped that as the therapist usually offers trauma therapy. I know exactly how you feel as I would often be gagging for sleep but would find that all I could think about was the labour - horrible horrible, but I promise you it fades in time.
