I know just how u feel. It is all just so fusterating and the pain is so unbearable and frightening. I'm so fearful of that pain. It's just so horrible and no one understands. I've went through many of those horrible, firghtening and unbearable times. It lasted all night and then the next morning. But for me mine, it wasn't D, it was the complete opposite and let me tell u the pain was so horrific I was literally screamin out loud. I don't even like to think about it because I am just so frightened from it. Belive me I know just how u feel and I'm sure many others experience that same thing. I do hope u get better soon!
