Start with one thing at a time.

Put down EVERYTHING.

Go and finish the bedroom.

Then... finish the SECOND thing that annoyed you.

Then... finish the THIRD thing.

One thing at a time.

I used to be like that, often! And I got SO annoyed with myself, until a girlfriend pulled me aside and said EXACTLY what I just said. One thing. First. Then another. Second. That way you don't get annoyed and frustrated, and end up in a vicious circle.

Huge soft and gentle hugs. And well done for getting rid of the bottles. And the plastics cupboard and the tupperware. Now go clean the bedroom.
