phobia-One of the worst thing in one's life???

http://phobialist.com According to the list, I have Belonephobia or Aichmophobia: a fear of needles.Z I am not scared of needles if I have them in my hand, but when other people are holding them, I panic. At the age of seventeen, I still need to hold people's hands when I get shots and stuff. I also have the fear of dying, which is Thanatophobia/Thantophobia.

I don't know this fear of mine is called phobia or what. It's not the height - let me describe the feeling. When I'm in a roller coaster, the feeling of coming down and you feel that your heart and stomach are falling down...that kind of cold feeling in you. It's terrifying - I am not able to enjoy rides that comes down with a great force...the climbing or going up is fine. It's the coming down....yukks!
