Alright, here's the deal. I was at an industrial site the other day for a tour. At one point, we were up about 150 feet on a platform with waste-high railings. These were horizontal tubular steel railings that were similar to what you find as handrails on concrete steps. I was fine at first, but after about a minute, I started feeling very uneasy - like I wanted to jump. I had to step away from the railing. I don't have this problem looking out of windows, only when there is open space, like a balcony or platform.
I'm 37 years old. When I was 26, I started having health problems that lasted for about 2.5 years, at the end of which I emerged with hypothyroidism. Why is this relevant? I don't know, but I'll get to why I bring it up.
Prior to the above-menitioned infirmed period of my life, I had no problems with heights. In fact, I used to drive my mother crazy by swinging out over cliffs or leaning over balconies, etc.
Anyone have similar problems or might know what brought on this condition???? I'm stumped and I don't like it.
