I have trypanophobia (aka belonephobia), fear of hypodermic needles (or, more specifically, medical procedures involving hypodermic needles).
It's actually a real, recognized phobia... as is phobophobia (fear of fear), mottephobia (fear of butterflies and moths), acrophobia (fear of heights), coulrophobia (fear of clowns), etc.
**Edit: Not that I have any of the phobias following trypanophobia, just giving examples...**
When I had my fillings done and my wisdom teeth removed, I had them done at the same time (to save time and money), and I ended up having a horrific panic attack at the mere sight of the hypodermic needle coming at me.
I hyperventilated, cried, screamed, and passed out.
I don't think when I'm on T, I'll ever be able to do injections because of my phobia.
