Most of my family knows, but only my parents fully understand how much it impacts me because they've seen it firsthand. All of my doctors know, but, again, they don't know how bad it is until I have a full-blown panic attack right in front of them (which has happened several times...I'm pretty sure I scarred my primary care doctor for life by temporarily losing my mind during my first visit with her. I knew I had found a good doctor when she just tried to comfort/ help me and never judged me for it, though.). I've told a few friends and professors, but only on a need to know basis. Even then, no one except my psych professor understood. I get a lot of responses like, "I don't like to v* either" and "Oh, spiders creep me out, so I have a phobia, too."
