Hello, I'm 49 in July and haven't had a period for a couple of years at least, so we are sort of the same age.
I was on the pill which regulated my moods anyway but I had 2 weeks off so they could blood test me and that was not fun - crying one day, furious the next..... I've just changed to HRT to see if that makes a difference. I'm not depressed, I'm happy and motivated, I'm just cut down by lack of sleep.
I'm pretty anxious anyway but it has got worse - where I live you can self refer to 6 week courses that teach you lots of strategies for coping with anxiety, and I think you can get reffered for Cognitive Behavioural Therapy (which is very sensible stuff) wherever you are in the UK. I don't know about the rest of the world though, you might have to pay for it.
There are a few online resources too -
https://moodgym.anu.edu.au/welcome is good - it says it is for depression but it is basically a way of learning to judge your thoughts and work out if they are realistic or not, so it's applicable for everything - anxiety, anger, sadness.......
I still get morbid thoughts daily, I think this is part of saying goodbye to youth and the fact that everyone seems to be dying at the moment, but I'm sure it's linked to the menopause. It feels better for me to be able to catch a daydream about my mums funeral (for example, she is not actually dead, thankfully) and I can just put the daydream and sad thoughts down to hormones, that helps me a lot.
And none of this is forever, things change.
