Thanks everyone. I have been away and unable to respond to you all.

I am thankful I am not alone.

I find the reply regarding BPD and delsuional thinking quite interesting. Before my psychiatrists finally arrived at the diagnosis of Bipolar, it was first suggested my MI was Borderline Personality Disorder. meanwhile, my CBT therapist copied for me her session notes. One time there was the statement "Pzchyzo Affective(?)"

Whatever. This is most unpleasant. It comes on instantly and subsides equally quickly. I feel rather sheepish afterwards as I try to explain to the other party my thinking and how sorry I am.
