I'm scared of quite a number of things, unfortunately.
Pain - I hate pain. I mean, I will withstand and endure a lot (mentally and physically), but I just don't like it.
Blood - It just freaks me out. Deep cuts and stuff, eugh. I can't watch RPA or any of those shows because when they operate they show all the crap and I almost puke.
Bugs - Creepy crawlies are creepy. I know they're minuscule in size and stuff, but still.
Heights - More like a fear of falling, but I just hate it. Even at school I don't stand too close to the railing.
There's probably a lot more. It's funny, because I never show any type of weakness at school. I mean, I'm scared of these things, but if I see a bug at school I'll kill it without flinching. I like to disguise my fears, basically.
