Acrophobia, Coulrophobia, & Trypanophobia

I'm pretty sure the first and last phobias were due to experiences when I was just a baby. Apparently, I was adventurous and mischievous so I often disappeared and could be found climbing something I had no business climbing, then falling. The last was due to parents letting my mandatory injections pile up, then having me get them all at once, which was also my first memory of a shot. Coulrophobia has no explanation, just every time I see a clown I try to book it.
