get a bug... in a jar (or have someone else do it), then go in a room where the bug cant run away and hide... let the bug loose, and just deal with it, you might freak out at first and get angry, but just sit there, deal with it, accept it, and you'll start to realize there's no real reason to fear it (unless it's a camel spider, those things are fucking huge and scary)... this just coming from the idea that the best way to overcome fears is to face them
