I am 45 years old and every month I go crazy and think I need to be in a loony bin is this the change?

If you are still getting your periods regularly every month and the emotional upheaval is your only symptom, it may not be the menopause. PMS is more likely - and this is worse if you are stressed. Try taking a magnesium supplement (Salus Haus liquid magnesium is very good) and a course of Stress Relief Daytime and see if this reduces your emotional mayhem.
