I also thought I will get to the other side naturally but sadly hot flushes were horrendous even 2 years after the last period. Now on HRT.
But just to add to the treatment discussion, I agree with Flossieteacake, maybe CBT is not the best treatment, counselling would be better as you would have a chance to talk about your past experience and work through it. I know many ladies find that HRT helps with mental health issues but I think that it is usually not sufficient. When we get older we gain more insight and become more aware of who we really are. We might have been functioning in the past but now we can really feel that something is blocking us from being whole, and these are usually past traumas. It's really good to get insight and counselling can help. Also we need to be kind to ourselves, listen to our bodies and nurture.
Unfortunately there is so much going on in the world around us, it's so sad to see the increase in anxiety and depression overall, and in children. I don't think we can assume that oestrogen can be a magic pill, but possibly, if we take more care about our wellbeing we might be able to make difference. Since I started meditating, stopped drinking alcohol, had counselling etc. I found some peace and I became a better person for those around me, so maybe that is a start.
