Scary Thoughts

This morning I read a news story about a small plane that crashed into a Ferris wheel at a carnival, trapping several people for some time. That's something I never worried about before but I will now, not that I ever go on carnival rides. But once something happens it becomes a rational fear, as opposed to an irrational fear dreamed up by a deranged paranoid mind. I only allow myself rational fears--hey, I was in therapy for years to get this far. Here are some of my rational fears in no particular order:

Naturally I'm scared of mice, but who isn't.
I am somewhat afraid that I will be driving down the road and a drunk driving the wrong way will hit me head-on, killing me on impact. Sometimes I worry a speeding ambulance will crash into me. 
I am somewhat afraid that one or all of my cats will be eaten by a larger animal in the woods behind my house.
I am sort of afraid that my son will marry someone who doesn't like me and I will never see him again, except at my funeral which of course means I will never see him again. This relates to my fear that my husband will ignore my wishes and give me a funeral, which I don't want because I'm sure I would look terrible.
I worry I will start eating all the foods I have denied myself over the years and "let myself go" and never come back.
I am fearful a shark will bite my legs off when I enter the ocean. In lakes I just worry about piranhas or other big fish with teeth.

Those fears are not the ones that keep me up at night. These do:
I am afraid my blood pressure will make my head explode; I would take a sedative as suggested by my doctor but I worry I will become addicted to the sedatives.
Finding a lump during a breast self-exam is scary, so I don't do them very often which rightfully scares me.
I worry the furnace in the basement will blow up and kill me while I'm sleeping, which of course keeps me awake.  So then I'll be wide awake when it happens, and I wonder which is worse.
