Ruminating/racing thoughts really debilitate me at times. I try to hold onto the thought that some days are better than others. Of course, there are plenty of times that these thoughts go out the window when the ruminating thoughts are so intense and race very fast. Sometimes DBT skills can help. High dose Seroquel helped for a while, but I tapered down a little bit due to some side effects. I might need to go back up 600 mg or higher in the future though, since sometimes things are bad enough where the benefits outweigh the side effects. I wish I had better input, but I really hope you feel better and realize how hard this can be, since I've always struggled with these kinds of issues and still do.
