I have been very light headed and dizzy with a little heart burn I'm weak

And your doctor says? Try a walk in clinic, your symptoms could indicate lot of things.

Aging obese drunk with prostate problems?
14 year old pregnant dehydrated girl eating fried foods?
Inactive menopausal woman taking too many medications?
How would we know. You haven't given any useful information.
PS- I just threw in the prostate for effect, to show that your symptoms alone are meaningless.
