I have to say that i am testament to the latest research being "a fat load of bollocks" and actually quite damaging, if women are shunning ADs because of it. Interesting that you suggested 5HTP, this is actually a building block of seratonin, which is why it is recommended, however, whether it ever gets metabolised to seratonin is not clear. A good proportion of ADs prescribed are SSRIs (selective seratonin reuptake inhibitors) which make the body make better use of the seratonin it releases. The consequense of this is more seratonin receptors are synthesised on the cells which receive it, they take up more and feedback mechanisms tell the "sending cell" to make more, so we actually end up with a positive effect from SSRIs even when we have stopped taking them. As someone who was living scared, almost suicidal and about to throw a fifteen year relationship down the drain, i can tell you, ADs WORK!! They are not for everyone and everyone reacts differently.
I did post a reply to this post yesterday but my computor crashed mid send and it obviouslyt didnt go through.
I think homeopathic and herbal medicines have a use too, however you must be careful not to mix certain ones with SSRIs as they can increase the unwanted side effects.
You need counselling i think, it is available on the NHS, maybe you could look on the SN board to see if anyone knows of sessions taylored to mums with children with problems. I think you need to exorcise the demons of the traumatic birth, i had a "traumatic" normal birth, but in my mind it was traumatic and it played on my mind for months and contributed in no small way to my PND.
So sorry you are going through this - i cant say i have any real practical advise, apart from, give the ADs a chance, they can make you feel a bit shit for a week or two but after that most people feel the benefit, i felt sick for two days, then i was fine, my DP said it was like getting the old me back. Try, if you can, to get out in the air every day, that naturally boosts seratonin levels, and drink plenty of water too, that helps.
Hope you feel better soon. xx
