To be honest with you, Jules, as far as I can see you seem in a very good place to me. If you read some of the stories on here how women much younger than you are suffering the most horrendous menopause symptoms, you should be more relieved that you are having a good menopause.
The only way forward for you is try and not to over-think everything and use the VA medication without worry, read all you can on Vaginal Atrophy, education is power.
