Another major major thing that helps me manage my thoughts (not sure if this was mentioned yet) but is journaling. When I'm manic I can easily reach 20 pages in a day, and that helps me get my thoughts out while also keeping me from doing something reckless (if I choose to do it, that is).
I guess this site could be kinda like journaling, but with journaling you can be even more open and not have to worry about proper wording and being understood.
I'm looking at my DBT worksheets and I'm seeing a few things that might help from the Mindfulness module. Like just looking at the facts. Distancing yourself from emotions (i.e. "it appears x is making me experience anger" rather than "I'm angry"). And avoiding judging your thoughts. If you find yourself judging your thoughts, don't judge the judging! I'd write more but Saco just laid down on my papers and is belly up so I don't want to disturb him
I have a "thought disorder" (Sza) as well, and find APs (in my case Haldol) help manage my thoughts so much better than any other type of med. I don't have any racing thoughts or bizarre thoughts anymore and that makes a huge difference.
