Hi, DragonSong. Sometimes one's emotions ARE all over the place! That's a legitimate "feeling". I would just "laugh" and tell myself I am a "mess" and change the "subject" in my head. If I am not able to do that, then I will literally change and do something physical; go outside and work in my yard or go to the store or library or other chore, etc. When I lived alone, I would get out and talk to someone, anyone (store clerks, librarians, go somewhere and ask for information, etc.) but make contact with the world that wasn't swirling in my head.

I was alway surprised when I was a mess, that going to work "helped" because I'd get to work and the literal/different tasks of my job would change my mess and organize me more/better and, of course, 8+ hours would go by and because all things change with time, my mood would be "different" in the evening than in the morning, kind of like it can be from the middle of the night to the next day, in the daylight.

If you don't like what is going on in your head. Stop it! If you are alone, get away from being alone and "thinking". I found the inside of my head was the worst place for me a lot of the time. Go join a diabetic, arthritis, fibro, support group or some other group based on an interest of yours and use that as an alternate focus.
