My dad recently recommended some books on dealing with anxiety by Dr Claire Weekes and so far I've found them quite useful! Actually I've only gotten 1 so far, Hope and Help for Your Nerves. It doesn't specifically deal with Pure O OCD (which is what I have) but it's pretty good in general.
I've also seen various threads here mentioning Dr Weekes's books and I was wondering - has she written anything specifically for OCD? It's not very easy to find information and resources about her writing for some reason, so my Google searches have not proven very fruitful. I was hoping someone here might know more.
