I was diagnosed with bipolar by my psychiatrist, and my therapist thinks I have OCD. I am certain I have a mood disorder and cannot take SSRIs and have OCD, but my therapist has not seen signs of bipolar and is skeptical of that diagnosis. Either way, I am in the situation of having OCD and not being able to take the traditional medication treatment. ERP is what the treatment will have to be for me, but I have heard it can be quite successful. Have you looked into it? I found the podcast The OCD Stories informative, and made me feel less alone in case you're interested.
