heavy bleeding and an emotional wreck

I'm nervous,and an emotional mess,my periods have been irregular for a few mos,and this month(7/4) it has been the worse its ever been,heavy bleeding with clots,and so it continues.Emotionally I am a wreck,Iam 46yo,I have no close friends to talk to.I called my OB doc,she ordered blood work,and a possibility of an ultrasound.I've visited my local health food store and spoke with the owner,she states,i may be menopausal.I am anxious and depressed.Will this month be last period,or is the worse yet to come?I can't get an appointment with my OB doc til September. I need a friend for some support...
