NB: I'm truly sorry that you haven't reaped much (any?) benefit from HRT.
It has been a godsend for me.
No, my personality has not changed form night to day.
At the core I'm still the same old me.
Emotionally, I am much more accessible, a shy smile will always provoke a big grin from me.
Somebody crying will cause that twitch in my nose as a precursor to my tears falling.
I am much calmer and have a much larger reserve of patience.
More to the point, I am happier.
Oh, yeah, then there's the physical and sexual effects too.
