Might you be able to find a different NOCD therapist who's comfortable treating most of your other conditions? I have several comorbidities too, and this has caused a lot of specialists to bounce me around... "I can treat your depression, but I'm stumped by your autism, you need an autism therapist." "I specialize in autism, but you should see someone else for the trauma." Honestly I think most of the time, the therapist just couldn't figure me out, so they punted me to someone else. I got really lucky with my NOCD therapist because she also has a background in autism, ADHD, trauma, and the type of emotional work that resonates with me. Your current therapist might be able to help you find a better fit. Even if a new therapist can't treat every single thing, they might understand your other issues well enough to keep them from interfering with your ERP.
Now, if by partial program you mean an intensive outpatient program where you go 40 hours a week for a month, yes, I've been in one. It definitely was the only priority that month. I had to clear everything else. But it did teach me a lot of important tools and frameworks. It had a Dialectical Behavioral Therapy approach, which emphasizes building a foundation for mental health by making sure you're eating, sleeping, socializing, taking your meds, treating your physical conditions, and practicing mindfulness. There was a psychiatrist who handled my meds. Different classes, some mandatory and some we could choose between. So there were classes for mindfulness, substance abuse, interpersonal health (like learning about boundaries), art therapy, and group therapy. And there was an AWESOME salad bar and daily hot specials for lunch. I recommend doing one of these programs if one is available... Fingers crossed that there's anything near you that your insurance covers. If there is though, ut is ABSOLUTELY worth taking an FMLA leave from work to do it. You'll get a solid foundation. Nothing else will get you further faster.
