mmm I have some ridiculous fears, as for example spiders, giant sea creatures and wind and other ones too: I'm afraid I'm only wasting time, I'm afraid I'm ruining other people's lives, I'm afraid not being able to face the fact I'm a failure, I'm afraid of regrets, I'm afraid of not being able to express myself, I'm afraid of my weakness, I'm afraid of not being of any support when someone asks for help, I'm afraid I'm more as others see me than as I see myself, I'm afraid of being empty and discovering it when it's too late etc...etc...
I'm the queen of banality
I also agree with Blue that mentioned the idea of being forgotten as one of her fears.
