Hi nan24, welcome to the forum.
Yes, I think you would benefit from resuming HRT and I don't think it is ever too late. I had my hysterectomy in 1997 and was given oestrogen replacement afterwards. Six or seven years later I was told I had been on it long enough. I was just 54 then. My GP refused point blank to prescribe any more. After a gap of 13 years, at the age of 67, I restarted and now use Oestrogel, Testogel and the Estring (the latter for urogenital atrophy). I am doing OK and stamina, mood, joint pains and libido are much improved, as is the atrophy.
Try to get your HRT back if you want it, don't let them rob you of any more years of your life. Transdermal preparations, patch or gel, are best for women in the seventieth decade, as they bypass the liver. If your GP is obstructive, ask to be referred to a menopause clinic.
Good luck, and let us know how you get on!
