Hi, I am a 53 year old woman, diabetic , had a very sedentary job for 18 years , being treated for chronic depression, and now i am experiencing terrible muscle weakness, fatigue , sleepiness, and it's been going on for the last 2 years. I'm also about 100 lbs overweight but I can't even walk 50 ft without getting dizzy and panting like hell. I want to exercise but my heart is weak and I have that condition where my BP drops whenever I stand up too fast. This is compounded by Milroy edema praecox from my mother's side . Unfortunately I have no insurance so I can't see my doctor about this. HELP!!!
