Retro:
I am not a professional by any means, but it certainly sounds as though you are suffering from PTSD.
It is an unfortunate feature of human biology that when we suffer a traumatic event, our bodies produce stress hormones which serve to "cement" the memory of the event in our brain. This is nature's way of helping us learn to avoid dangerous situations in the future. Unfortunately, in a situation like yours, this means that an activity you love--cycling--now has a very strong negative associations in your mind. This was only compounded by the subsequent cycling accidents you endured.
What to do about it?
If nothing else, stick with the EFT you've been practicing. You yourself stated that it seems to be helping. You have been able to go on
some long rides. When you are able to complete a ride, take some time to review the ride in your mind. Reflect on the positive things which came out of the ride. In this way, you are reinforcing the positive feedback from the ride. This will help to degrade the negative associations (actually, a negative neural pathway) in your brain and help build new, positive associations (neural pathways) in your brain.
Cognitive Behavioral Therapy (CBT)
I am a huge believer in CBT. Several years ago, I read two fascinating books about the recent research in neuroplasticity--the ability of the human brain to grow new neural pathways:
The Mind and the Brain, by Jeffrey M. Schwartz and Sharon Begley (see the Amazon.com entry at

The Brain That Changes Itself, by Norman Doidge, M.D. (see the Amazon.com entry at
http://www.tinyurl.com/7n93xnd .) In particular,
The Mind and the Brain has a long chapter which discusses how modern cognitive research has demonstrated how CBT helps get rid of negative neural pathways and grow new, positive neural pathways. A superb introduction to CBT written for the popular audience is Dr. David D. Burns'
Feeling Good: The New Mood Therapy (see the Amanzon.com entry at

Hypnosis
Forget all the unfortunate stereotypes about hypnosis which are perpetuated by the media. A competent professional hypnotist can help his clients rid themselves of deeply rooted fears and phobias. Here's a link to a wonderful "TV Magazine" story about hypnosis. One of the stories in this video is how a young woman with a debilitating fear of spiders was cured with the aid of hypnosis (just click on one of the links immediately to the right of the camera icon in the middle of the screen):

Meditation and/or Yoga
It has been demonstrated that these disciplines also help one grow new neural pathways in the brain. If nothing else, they are superb stress relievers.
The best of luck to you. I sincerely hope you are able to find a solution which will allow you to enjoy cycling like you used to--without the stress.
