Been ill for a year, many tests..MRI, CT, Holter, EMG, EEG etc...

my symptoms started as a complete collapse one year ago...apparently was stuttering apon awakening.  After the collapse I had very bad vertigo, and headaches, my vision is terrible..no depth perception.  I also have no nerve response in either foot, a lot of leg cramps..charlie horses, and numbness, tingling and searing pain in my feet.  I now have problems in my hands..I stumble alot and fall.  Eating habits have changed...small portions at a time, or severe stomach cramping, and or vomiting occurs.  I am tired all the time, have trouble concentrating and finding words when I speak, get things mixed up and am extremely forgetful.  They have diagnosed me with Neurological Chronic Pain and symptoms of MS.  The clincher is,,this past Friday I had a 75 mg GT test and fasted for 12 hours.. yesterday they tell me my glucose level was 9.8 and I need to see a dietician..could all these previous health issues be caused from being diabetic and not being treated?
