I have the type of phobia you can control with this, well sometimes. I've actually just turned 13 and when I was in 7th grade I would get so scared I would get sick and sometimes throw up a bit. After awhile my doctor upped my depression med and told me I needed to suck it up. Which was hard. Because I was very afraid of school and I had probably missed over a month of school because I was so scared.

But that was about the only experience I had.
