Needles and really sharp things, like maybe knives and stuff. But mostly needles. I hate injections. No matter how necessary they are. I don't donate blood. Don't look at me like that. I don't. I can't. I know I'm a bad person or whatever but IT'S A NEEDLE FFS!!! I'm sure it's not normal. I 'donate' enough blood once a month, I don't need to put it in a little bag too.
Other than needles... dirty hands. I hate dirty hands. Or being dirty myself. I can't handle it.
