Let's see...
I've got a little bit of arachnophobia. Not so much the spiders themselves, but just walking into their webs. It freaks me out because it surprises me, and I don't know if a spider is on me. When I was young, I used to hold my bookbag in front of my face when I walked through my neighbor's backyard on the way to the bus stop.
I've also got a case of acrophobia, but if you put me in a plane or on top of a mountain, I'm fine. Put me on top of a small ladder with nothing to grab onto, and I start shaking like a leaf. I dread having to change the lightbulbs in my garage, today.
On a more obsessive-compulsive note, I've got Ataxophobia (fear of disorder or untidiness), which I exhibited when I got back from Florida, last night, just wondering what I was going to find in my house that one of my wife's friends either screwed up or broke. The house was pretty much clean, but I still found plenty of discrepencies that bothered ME.
While on the topic of obsessive-compulsive, I've got Atychiphobia (fear of failure). I'm so afraid of doing a half-ass job that I'll spend forever working on the tiniest of details.
Also, I don't know if you could say I have the fear of being alone, but if there's a fear of having no one to turn to in a time of need, I've also got that.
