I Am 55 And Am Just Getting Into Menopause (I

I am 55 and am just getting into menopause (I believe). I still have my period although very inconcsistent; sometimes twice monthly sometimes nothing for 2 months. This has been for about a year. Hot flashes very seldom, although I am very warm at night. My primary question is my disposition. I am extremely hard working and very active, however over the last few months, I feel discombobulated, confused and don't want to leave my home. This is NOT me. It appears to me to be symptoms of menopause..is it? How can I help myself (without prescription drugs) get past this?
