Best Treatment for Comorbid OCD/OCPD
So, I have both OCD and OCPD. I've had OCD since childhood, and it going untreated (combined with trauma I won't get into) led to OCPD developing. I'm formally diagnosed with both and I am undergoing DBT for my OCPD, but my OCD is relatively untreated.
For one thing, my OCD these days can be fairly mild. Visualization and meditation is usually enough to handle the compulsions and obsessive thoughts. Keyword, however, is usually. If things are going poorly in my life, or if my OCPD is spiralling out of control, the OCD symptoms can severely worsen. People often imagine that the ego syntonic nature of OCPD means you can't have both, but in reality it simply means the thoughts are different. The fact I need to be perfect is not distressing to me (other than when I fail to live up to that standard, inevitably, which is the main cause of distress in OCPD aside from interpersonal issues). Meanwhile, my OCD obsessions are very much dystonic, and related to completely different things (if I don't snort, I'll say a slur being a common obsession, obviously dystonic, obviously distressing)
Here comes the issue, though
The most effective treatment for OCD is ERP as you know. But some studies have suggested that ERP is specifically ineffective in Comorbid OCD/OCPD cases; worse, even when it does help with the OCD, it will simultaneously make the OCPD worse.
So at the moment my treatment is using DBT (dialectical behavioral therapy, common in treating pretty much all personality disorders) to treat my OCPD. because my OCD improves when my OCPD is under control, my therapist and I have decided to focus on treating the OCPD and only mitigate the symptoms of OCD as they come up.
But I don't know if this is working anymore. It did for about a year, but stress in my life is getting worse. And while I am doing DBT, and it's greatly helping with my perfectionism and anger issues, my OCD symptoms are remaining constant -- if not worsening again.
Does anyone have any advice? Am I mistaken on ERP being ineffective in Comorbid cases?
Also. In advance, I don't want to see any negativity wrt OCPD here. I've seen some posts and comments on this subreddit more or less demonizing OCPD as "OCD but you harm others instead of yourself" which is extremely reductive and a harmful belief. I am asking a question; please don't project your experiences with other people with OCPD onto me. Focus on the question please.
