Do you have this phobia?

This is one of those things I feel is worth mentioning. Do you have a phobia? Most people do. I have a fear of heights. It can be crippling. I went to the water park with my granddaughter recently and we had to climb some stairs for a waterslide. She was running up the stairs while I was moving very slowly. My knees were weak, my hand was tightly gripping the rail. Once at the top we had to wait for a girl who was scared to go down. I was telling her to hurry, just so I could get my feet on the ground, quickly.

I have another phobia, which I feel is pretty rare. For lack of a better term I will call it Backtothefuturephobia. Sometimes when crossing a street I have the fear that a time machine automobile might come out of nowhere and hit me. Could it be Delorianaphobia or McFly Mania? If anyone else has this phobia, please start a support group.
