Q:I'm not scared of spiders anymore. If I see one than I can kill it easily, but when I see a daddy long legs crane fly, I freak out! Those things are hugeeee. I could never kill one without being freaked out to death. I heard that they don't even bite, but I'm still scared. There's one in my living room and I ran out. So I planned on staying in my room the whole day and just hope it doesn't show up in the bathroom tomorrow morning when I shower! I'm 14 btw?

This is a selective entomophobia. Basically, you don't fear many insects or spiders, but specific ones trigger your anxiety. Your problem is not the bugs or spiders,(they are harmless) but your fear. This is something 'you' nurture by dwelling on this fear when you see one of these particular critters. I'm glad to hear you no longer fear spiders. you will see the same when you overcome your selective fear. You may even come to realize that the spiders and insects you do fear,are totally harmless, and you may reach a point where you can just ignore these. True, the crane fly is totally harmless and do not bite, sting, or inflict any form of hazard to humans. They can be a nuisance buzzing around your face,as they can be persistent. Adolescent years seem to be when phobias are the most prevalent, but also the easiest time to overcome fears. If you can learn to control your fear, rather than let it control you, you will overcome this. you also need to refrain from dwelling on your fear,as this will only make it worse. Last year, one of my favorite pass times was sitting on the porch watching the sunset. a little orb weaver would come from behind the light and spin her fancy web. Often, I would catch a crane fly that was bothering me and toss it into her web.
