I needn't pretend to diagnose you or help you self-diagnose.

But as for the first one. Imagine you are at sea on a raft. Around you in the sea are bits of flotsam and jetsam. Sometimes they come alongside your raft for a while before they gradually drift away. Most people whom I hear from, get what I call mental flotsam and jetsam. When I get it I say to myself, well that's a fairly daft thought, I expect it will gradually drift away, and it does. The main thing is not to take it too seriously - not to own it - which would be dangerous to do. Are we right in assuming you wouldn't actually consider harming anyone?

The middle one (about 10s) sounds to my amateur ear a bit like an obsession! On my own obsessions I found the book "Brain Lock" by Dr Geoffrey M Schwartz lifechanging on just one reading, it offers such a simple programme. When out and about I say to myself, well it can be fun only stepping on cracks but on this occasion I am going to walk in a simple fashion.

As for the third, I think it is quite level-headed to expect people to clean their hands well in your space. Do you ask them to do so in a straightforward way?
