Hello mori-girl: Well... I don't have a proper diagnosis of anything. So I can't really offer you definitive advice with regard to this.

However here's a link to a video California family therapist, Kati Morton, uploaded onto YouTube regarding how to address intrusive thoughts:
Here's a link to another of Kati's videos on the subject of "Pure O" (OCD)
And then here's a link to a Q &A on the subject of HOCD from PsychCentral's "Ask The Therapist" service:

Hopefully these links may be of some benefit.
This appears to be your first post here on PC. So...

to PsychCentral… from the Skeezyks!

May the time you spend here be of benefit.
PsychCentral is a great place to get information as well as support for mental health issues. The more you post, & reply to other members’ posts, the more a part of the community you will become.

Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
