My most problematic phobia is a fear of vomiting. ): I got violently ill when I was seven, and it's been something that's actually terrified me since. It can get really problematic, since apparently ever TV writer in history thinks getting sick to ones stomach is a punch line. It's something I try to hide for the most part, and usually do a pretty good job of doing but if someone around me says they feel like they are going to vomit, that's.... one of the hardest positions I have dealing with, I'd say. Next to me feeling as though I'm about to get sick, but I'd rather not go into that. >.<;
Other notable runner-ups are of course creepy crawlies. I hate spiders and anything that buzzes and has a stinger, though I've gotten better about running away screaming in the opposite direction every time I see one since I've started working in the yard. =D'' As you can imagine, that gets unpractical rather quickly.
