I need help coping with menopause?

I'm 53 and stopped my period 2 years ago. I've been getting hot flashes, night sweats and mood swings so bad lately. I get so furious that I want to smash someones face in. This is not me! I have no insurance and haven't been to a doc in a long time. Any suggestions on what I can buy or do for this?? Please, I'm at my wits end.
