What am I afraid of?

What am I afraid of?  I am afraid of fictional characters who cheat.  I am afraid of a woman getting caught in the act.  I don't know why I feel this way.  I don't understand why I am so afraid.  I don't know why I have these thoughts about infidelity, even fictional characters.  I didn't always have those thoughts.  Right now, I am doing fine.  I guess it is because I am afraid.  I often hallucinate about my greatest fear, which is being bitten or being crawled on.  I am afraid of even writing what I am afraid of.  I am afraid of even the smallest one.  I hate being so afraid because of the fear.  How do I overcome that particular fear?  How do I avoid them?  Why am I so afraid?  There are questions that I have about them?  I wonder if there is an unfounded fear.  I am afraid that they will crawl on me. I see the evidence there which means it was there.  It has nothing to do with infidelity.  I will try to overcome them.  I will try to overcome the infidelity thoughts.  I am just afraid.  I have been in fear ever since I was a child.  I am saddened that I have this fear.  I look around and I see them, even if there is no evidence that they would exist.  I cannot take these hallucinations anymore.  I am afraid to go to areas where they may be at.  I isn't paralyzing but I am glad I have a cat in this situation even if he spends most of his time asleep.
