I know all to well how you feel. BUT, what I will say, is when I was going to a therapist years ago, disconnection is on of the body's ways of dealing w/ stress. It sucks for us, cause w/ the ocd you tend to interpret that feeling as crazy (and why wouldn't you, it feels different and out of the norm).
I'm not always stronger than my OCD, as it still gets the better of me, but what I have learned is those of us w/ OCD are very aware of our bodies so any differences or strange feelings tend to get categorized as wrong and / or crazy.
What I did for a while, was I kept a reminder card that listed the symptoms of panic and used reassuring lines from books I had read. I had trouble sitting in meetings at work behind closed doors. I kept that in my planner (for no one else to see of course) and would read it before my meetings and would peek at it during if need be.
I wish we could push an off button to ocd, but we can't. Panic and anxiety aren't easy, but I have harming thoughts for my ocd and I think it is the worst thing to live with. I am so ashamed of my thoughts and I feel that if people knew what I was thinking, I would be alienated from everyone and everything I love and know. At least panic is something many people feel, even if they don't have a problem w/ it. But w/ OCD, the thoughts are like a horror movie and the feelings of going crazy are just awful to deal with.
Please feel free to write to me if you want to share any other stories. I have been thru this for 8 years now and it's never easy dealing with, what I call, the "ocd zone". I've never been on meds, but did go to therapy for several years. I worked on cognitive behavior therapy and did a lot of online research and read many books.
Best wishes to you,
Laurie
