Hello Bev.
So sorry to hear you are suffering from this horrible menopause mularky. I know exactly how you feel, the not wanting to go far from home, feeling overwhelmed and withdrawn, even the gagging, all very familiar to me.
You mention blood tests and ladies here will tell you that there are notoriously unreliable as your hormone levels will change hour by hour, apparantly GPs are supposed to be guided by symptoms when diagnosing the menopause.
As for HRT I'm not an expert but many ladies on the forum are and I'm sure some will be along shortly to advise you. Hang in there, you are not alone!
Take care.
K.
