I had total hysterectomy 20 years ago and was only given h.r.t to relieve awfull menopausal symptoms. I took them for over 15 years. However they don't tell you that when you eventualy stop them the symptoms all return.
I think they might have been easier to cope with in my fifties than they were in my sixties.
I can tell you that once everything settles down, at least in my case, even in my sixties, your sex drive returns.
Despite h.r.t, for the first year or more after my hysterectomy I had little or no desire for sex and I suspect that, subconsciously, my body was saying "whoa... we're feeling very delicate in here" You have had realy major surgery. Give youself a chance.
(And when you do, once again, feel desperate for it remember to protect your thinning skin with some moisturiser and use something like a little KY jelly at the time, or you will put yourself off it again)
Good luck the setback is only temporary
