Dear Janet, Welcome to HealthcareMagic!
The weird symptoms you are suffering may be due to a number of causes. Single blood test
cannot diagnose all. I think, you Ist get your BP checked; then blood glucose
function test should also be performed. For this, I advice a complete & unhurried check up by a General Physician. If all is well, then this may have a psychological cause, most likely endogenous depression
. This is also completely treatable by modern drug therapy. Good luck.
