Oh like you are SO focused on your thoughts thry don't feel like yours anymore? Even though you know they are?

I have not and do not experience that
and when i do dissociate I do go away! I have also had that thing where i feel as though I'm observing myself ftom outside my body ect.

I would say having anxiety and OCD myself wbat really belped was learning CBT. What your going through may be a different type of depersonalisation as your T says. It could also be analytic OCD thoughts... hmmm interesting. You may want to post this on the anxiety and OCD areas too. I was reading through those the other day and saw SOME of the people disspciate when they have panic attacks. Keep posting here too of course! and if you ever want to tslk privatly you can PM me.
