Hi Kennish:
I'm really sorry to hear how much you're suffering. I'm definitely not suggesting that it's all in your head. I BELIEVE everything you say is really happening to you. I'm just exploring whether it all stems from the obsessions in your head. I know all too well the mind body connection when it comes to OCD. I can for example make my hair fall out by obsessing, or even my teeth to be honest given enough time. It's very real the power of the mind.
Here's some more info on ACT:
