Can Irritation, Anger And Behavioral Changes Indicate Onset Of Menopause?

Am I prementapausel?
I wake up angry,I am irritated thruout the day. I feel like I am going to explode.
I am usually a very nice person and like to give huggs and I love my friends and enjoy seeing them. But now I would rather be at home because I cannot stand to be around people because I cannot seem to make myself feel better on not be angry and irritated. Please help me.....
