I´m also afraid of heights and I have a phobia of slugs / snails. I know they can´t do anything to me but I find them utterly disgusting and I don´t want them to be anywhere near me.
Do you know how satisfying it can be to overcome your fears btw? I remember well the one time my best friend convinced me to try and ride a scary rollercoaster together and we also went into a ferris wheel afterwards. Felt so proud and it was indeed fun which I didn´t expect before.
Other fears I have is drowning, choking, disappointing people or losing them.
