Hello there. This is my first post here but I'm compelled to answer as you sound similar to me in some ways. Firstly may I extend my sympathies at being bereaved. You have had a lot to cope with aside from the hormonal and anxiety matters.
I was also getting in a stress muddle worrying about HRT and symptoms etc. Like you, I had the Mirena coil for years and didn't know where I was with perimenopause as I hadn't had periods since getting it. I was anxious and struggling (some circumstantial stuff going on that would have exacerbated, if not caused this) and my GP suggested starting Oestrogen. I tried all different routes, gel, spray, tablets and patches and found myself worse on it. Each time we discussed it, the doctor increased the dosage and I'd get tight-chested and start coughing and cut it back down after a couple of weeks and when we next met, she'd prescribe a different type. There was an undeniable connection with worsening symptoms/ side effects/ whatever and increasing the oestrogen.
I went to a private menopause specialist who suggested adding in Utrogestan. I took it for about a fortnight and felt wonderful! Like my old self. And then I got really sick again. I couldn't eat without bloating, I was constipated, nauseous and my health anxiety went through the roof. I was constantly speculating was it the oestrogen, the progesterone, was I too high in one or both or too low etc etc.
Eventually I was so annoyed with myself and my constant speculating that I decided to wean off both hormones and then get the coil out. Like you, I wanted a good few months to see what my body was up to without the HRT and coil obscuring the picture. That was all done and dusted mid-June and I have since recorded two cycles with periods and I'm now late for the third but feeling premenstrual. This feels like useful, reliable information! I have been far less anxious and the perpetual questioning has stopped - what a relief. Unfortunately I have had a return of disgusting migraines with dizziness and nausea, I'm tense as anything and the insomnia cycles round in phases. I'm better than I was but I'm still struggling hard at times.
I have done lots of reading and thinking. I overhauled my diet last year and finally figured out more or less what my guts can and can't handle, which has helped enormously with digestive issues. I have found certain yoga moves that can alleviate the headaches and sometimes when the dizziness is bad, I resort to taking a vertigo tablet so I can cope with that. I'm lucky as I work from home and can schedule a nap or break to relax if I've had a naff night. I think stress plays an important role - I do too much - so I try and plan tea breaks and pit stops.
Having considered the past few years, the prescriptions, the symptoms, the change of approach this last four months, I have come to the conclusion that I don't currently need oestrogen but I benefit from topping up progesterone a bit. Some parts of the cycle I feel great; other times dreadful. I honestly believe progesterone has a beneficial, mellowing effect on me.
So I am therefore going to continue the natural approach and avoid full HRT at this time, focus on good diet, yoga, relaxation, but I am going to try a progesterone cream, which I gather is mild. I ordered some cream this morning and will give it a whirl.
Not all together a proven solution yet but I totally relate to the wanting a break from the drugs and seeing what's what and trying to devise a personalised, more natural response to the challenges.
I wish you well and hope that the counselling provides helpful support too.
