Fingers crossed my mood still seems to be improving after my awful depressed/anxious episode of the last week and a half

And, I am very, very grateful that (hopefully) HRT will really help even out my mood swings/anxiety etc.
But since starting HRT, even when I'm having a 'good' couple of weeks I am very aware that I'm not precisely the same as I used to be before this peri roller coaster started. It's very subtle, and I think only I would be able to tell the difference but I feel like a 'photocopy' of my old self. A photocopy that is just very, very slightly out of focus.
I also feel like I have taken two steps sideways and one step backwards from where I used to stand before peri menopause.
All my peri menopause symptoms have basically been anxiety/mood swings/low mood and insomnia. So 'all in my head' so to speak. None of the classic physical symptoms yet (other than much lighter periods, closer together).
I was wondering if I now feel like a 'photocopy' of myself because I am still suffering the echoes of nearly 18 months of anxiety/depression and mood swings? Or whether it's the HRT that is making me feel this way?
I am wondering if it's the HRT because this slightly muted, disconnected version of myself that I nnow feel, feels quite similar to how I felt when I took ADs when I had post natal depression. And my post natal depression mainly presented as extreme anxiety and feelings of hopelessness too, which makes me suspicious.
Just wondered if anyone else felt the same (I know Greenfield does) or whether they had any thoughts?
