I definitely have diabetes and PD, but I think something else is going on too. Every day I feel so weak and fatigued. I don't think it is the meds because I have been on diabetic meds for 15 years. And the exhaustion started way before taking any PD meds and the meds for my BP I have been on over a decade. I have had all my vitamins checked and metals in my blood. I take B12 shots, I take prescription potassium and Vit D. I'm only 68. I really think something else is going on but every time I bring it up at the doctors office I am told to exercise to build myself up. Believe me I keep trying but a day doesn't go by that I don't feel like I am going to collapse. Also I weigh 135 and am 5'2" so it is not my weight that is the problem. I use to be very energetic years ago. It all started around 2006. I know because I had to retire in 2007 because I just couldn't handle anything any more. I would have to go into the ladies room to rest. Before then my fellow workers had trouble keeping up with me. Could this be part of the PD?
