Suggest Treatment For Mood Swing,insomnia And Anger After Menopause

i am 48yr old female and am menopausal and not taking any medication. Recently my behaviour has changed considerably whereby i initiate inapropriate conversation with strangers, have terrible feelings of doom, have visuals of myself slipping on our stairs (which are pretty treachorous), swear uncontrollably, show complete insensitivity to friends followed by enormous guilt whereby i withdraw from contact with people, am constantly angry about world issues, read papers from the end to the beginning (paragraph by paragraph), have feelings of being "out of control", insomnia, complete lack of tolerance for mankind and i could go on. What the hell is wrong with me? Wendy Race, Bath United Kingdom
