Just remember it is ALL OCD. It doesn’t matter what ‘flavour’ it is, you deal with it as you would do any other OCD intrusive thoughts.
My ‘usual’ OCD is paedophilia but have also had bouts of ‘harm’ and ‘contamination’.
… but yes, it can be very distressing when a ‘new’ OCD presents itself or even a new intrusion for the ‘usual’ OCD.
Don’t overthink the ‘new’ intrusions- it isn’t a sign you are getting worse (as I made the mistake of thinking). Don’t try to make sense of it - dismiss it and try to get on with your day !
