Does anybody have a fobia?

I am extremely claustrophobic! The doctors have to totally sedate me to do an MRI! Also I am terrified of heights...I even have problems getting on a step stool! I did finally cure my phobia of snakes and lizards. I really disappointed my grand daughters when they brought a baby lizard in the house, they expected that I would scream and have fits...and I simply petted the top of the lizards head and then we turned it lose.
