Just asking to confirm my worries. My thought process is, well, I think of the most horrible possible sensations, thoughts, scÚnarios and fears and they run through my mind and get worse and worse. Like I think this is it, this is the end I can't stop this now, can last for a few mins to a few days.
Really scares me and I just don't know what to do. Has been happening on and off for 12 years
