Red1970 Welcome to Gransnet.
I think the clue to your problem lies in your words - feel that all the information on the internet is confusing me. Back in the day, when the only source of medical information was the family doctor, us oldies tended to believe what he/she said and duly took our medication or treatment regime and generally recovered sooner or later. What we were spared was endless nights, worrying about side effects and reading more scare stories. Has it occurred to you that commercial interests are at work here - spreading scare stories about treatments in order to sell their own alternative remedies?
Your GP will have checked that you are a suitable candidate for HRT and will keep an eye on Blood Pressure, etc. while you are on it. It does not help everyone, but you do say that your troubles started when you came off
. I cannot advise you what to do. I only know that for myself and many other Gransnetters, HRT allowed us to continue to work and live a full life through the menopause and we survived to tell the tale.
Best wishes 
Retiring and living frugally in money from downsizing after years of stress
