I know some Thuja's case with an obsession of this type, the hands being washed compulsive by fear to the contagion of any thing.
Thuja has as axis what in my opinion has this person: obsessive thoughts.
Thuja it wants to have it under control. It takes anxiety as his health, fixed ideas and it sits down fragile, (of crystal). So vulnerable that any thing can affect it, Thuja sits the death always in his shoulder. It wanted to be incorruptible, but it sits down very fragile, any thing can affect him. In his imbalance, it exaggerates this and a fixed idea turns.

You could have understood me?
