What Causes Hot Flashes With Lack Of Energy And Depression?

In the last few weeks, I have started having like a hot flash in my neck and checks; almost like I m blushing. I suffer with lack of energy, depression and anxiety (grieving loss of spouse of 30 years and mother) but this is a new situation. Currently being treated for high blood pressure with HCTZ in the morning and Norvasc at night. I take vitamin D (5,000 IU) daily along with CoQ10 and Xanax PRN. I m 64 and thought I had gone through menopause already. Could this be the anxiety/depression and if so, what supplement could I take to help. I have no insurance so medical testing is not an option at this time.
