Whenever I get a thought that is triggering or causes me anxiety/stress, I tend to cover or plug my ears and sing “dum dum dedum dum” or something alike. sometimes I also just let out any sound that comes into my mind, maybe the equivalent to ‘assfghkhkmdjsjrjem’. At times this prevents me from spiralling into a mess, but for other people around me it looks like I’m having some sorta psychotic break. 
Just wondering if anyone else does this and if it helps them?
