I'm intrested in this as well . There is the hyperfocus that can appear as obsessive.
The obesessive compulsive part to me is the intrusive thoughts that lead one to do things and one lacks control over having to do them .
But if its an addiction theres that component . If its fear driven its OCD .
This can be anxziety driven also. I'm not real savey on meds. Having my eating disorder classified /calssifies me as obsessive compulsive . I was on Prozac for several years.
Its a puzzling, trying to tease apart ADHD and OCD .
I'm trying to learn more about ADHD . Particularily the visual component both the outward visual distraction as in objects or written words. And with the internal visual distractions that are word connected .
maybe start a thread on it over in The ADHD section . if we can steer Colleens trike over there..
Or here . Shucks , now Im conused.
