Petrified of bananas

So yesterday in college we were making banana bread as I do bakery in college and I already knew I was scared of bananas but I thought I would be okay if I just didn't touch them of look at them but I asked to stand outside for a minute and the lecturer came outside and asked me what was wrong and I burst into tears and told him I was scared of bananas but this can't be normal I am so petrified I can't even be near them and I mean actually crying over this does anyone else have any 'Irrational ' fears that are completely rational in your head because I felt so silly yesterday
