I am a 48 year old woman and have just started having a few dizzy spells.?

I am wondering if I am perhaps anaemic as I am going through the menopause. I do eat a fairly balanced diet though. Or perhaps low in blood sugar. There is a family history of diabetes. I do get heart palpitations from time to time. Or could it be stress related. I have just moved to Australia and I lost my mother about 4 weeks ago.
