You are not alone. I was rearended and this is right before being diagnosed with Addison's disease. My car was totaled and I did pass out during the accident for a few seconds. So I have such a fear of driving by myself or even driving now. I would be afraid of being alone and getting hit and not being able to get to my meds and dying. In emergency situations I am not sure how my adrenals would act do to the Addison's diagnose.
Plus to drive a distance would just be to much on me for the fatigue.
