Carnation, you are an absolute star!!
I'm new to this site. Well that's not true I've been a voyeur for years, but have never bothered to post anything myself. I've been feeling so bad of late that I came on here again just to look, but I saw your opening post of this thread you wrote back in 2014 and nearly burst into tears. You described me and my symptoms perfectly, especially the floatiness, unstable ground and heavy head, not to mention of course the hypervigilance.
It is amazing to know you are not alone!! I'm a recovering alcoholic and I remember my first meeting of AA, many moons ago now, gave me that same feeling of not being alone.
It is fantastic that you have carried this thread for all these years. I'm sure you have been a great help to many many people as you have been to me today.
Love,
Medesis
