My update...

Well, I saw the GP all the other mums at baby group warned me about....he was not much good at listening though he did prescribe me cream and tablets to try and sort out the infection/excema on my foot, he's also upped my antidepressants and is pleased that the health visitor has refered me on to the mental health team. He was so grumpy, will definately try and avoid him in future...

I am feeling a bit better knowing that things are happening (and that the munchkin's birthmark is ok) and hopefully we'll find some reason why I'm struggling with things, it doesn't appear to be simple post natal depression
