Like "Dear Friend ... I am so sorry about what you have and are going through. I completely understand the fears, feelings and frustrations. You have certainly had some tough battles with your health. Please let us know about the MRI results. I just don't know that I have much confidence in an Ophthalmologist being able to determine MS. Your worry may be putting more stress on your body. I had a doctor suggest that I quite possibly had Malaria. I didn't. "
