Personally I will be on hormone therapy for the rest of my life, as there is no age at which I am ok with developing osteoporosis or any of the other diseases of hypoestrogenism, and no age at which my quality of life ceases to matter.
I had 7 affected relatives and was lucky enough to qualify for risk reducing mastectomies at 29, so this may be something that is available to you too if you have a strong family history.
I would much rather have estrogen than breasts, in fact I was willing to pay a lot of money to have my cancerbags removed had I been unable to get the surgery on the NHS!
It has given me probably as much psychological relief as the BSO gave you.
I elected to keep my ovaries and take the combined pill for 20+ years to halve my risk of that, and pay for private screening, both of which I have continued despite learning I was negative when genetic testing became available.
Regarding symptoms, some women do experience a return of symptoms if they stop or reduce estrogen, others don't. This probably depends somewhat on whether you had symptoms to begin with or are taking it predominantly for health reasons.
