Oh, wow! I didn't see this thread before I posted in your other one.
I think you may be having minor panic attacks. Your symptoms sound almost like mine. Anyway, please see your doctor.
Also, researchers are now touting the multiple benefits of Vitamin D now. They say the government daily requirements are too low. We should all get 2,000 IUs for maximum benefit, and there's no fear of overdose. Just read about it today in an older Newsweek magazine in the health section. Somehting to think about anyway.
Shalom!
