Notice how when one worry is finally settled, another takes its place. That pattern is the thing you are actually dealing with, more than whichever worry is currently in the chair.

If the urge to arrange has to go somewhere, point it at something that can actually be finished. A kitchen drawer ends. A desk you keep re-sorting never does.

If this has been going on for years, medication is often part of what helps, and it usually needs a longer run at it than people expect. Starting low and building up slowly is the normal way of doing it.

Plenty of people quietly believe that thinking about something bad makes it more likely to happen. It has a name, it is a known part of this condition, and having the belief does not make you dangerous.
