Hi,
I have spd too. From what I understand, being emotionless is part of the progression of the schizoid trip, we get 'exiled' from other humans, then 'exiled' even from our own feelings.
But I believe healing is possible if you want it.
There are 2 of us here in London who id with schizoid and weve been having a weekly study group, - just incase you're interested.
I'm the same as you said in that other post, I get phobic about anybody clinging to me, feels like being stiffled or drowned.
all the best,
riverx
