It does seem like hormone fluctuations can exacerbate symptoms. I went through perimenopause as I was withdrawing off anti-depressants, and it was absolute hell, but I kept trudging through. Then I went through Klonopin withdrawal and that was/is level beyond hell. I am still suffering. I am now post-menopausal for a few years, and am mostly through horrible menopausal symptoms coupled with benzo withdrawal. I can't believe I survived going through both things a the same time. My doctor thinks my severe withdrawals actually brought menopause on earlier because of the severity.
The withdrawals created chemical sensitivity, so I can not get hormonal support either or they will send me into horrible waves of symptoms. Overall, it think its best to stay away from hormone support right now until you feel more stabilized, if thats something you wish to do.
I wish I had advice or a vast repertoire of hormone knowledge to impart, but I think just hanging in there is the best course. Our female bodies are extremely sensitive to hormone fluctuations, and they affect neurotransmitters, so it only makes sense that benzo withdrawal symptoms could get activated. Hopefully, your brain will heal more as you step into menopause. There are some wonderful advantages to menopause...
