I used to be uneasy around heights, small spaces and spiders.
I now love heights and dangerously leaning over them, looking down. I do not really mind spiders, they are not my favourite animal but if they are in my way, I pick them up and remove them without a problem and think they are somehow fascinating.
The only phobia I am afraid I will always have, is claustrophobia. It is not the case that I go crazy in an elevator or whatever. Just when I am enclosed, I freak out. That is all.
