Thank's for clarifying that Jude.I have vertigo and the last attack I had knocked me flat on my back.During the actual attack I really thought me and the stove were going to fall through the kitchen wall I crawled on my hands and knees to the couch and remanined imobalized for the rest of the day.
Maybe the fear of hieghts is attached to vertigo becasue if you ever had an attack up a ladder etc......
As for it steming from CSA I don't know either.There was a lot of physical abuse in my life as a child. Maybe that contributed to it.
