Hi Sandi, I'm so sorry you're going through this. I completely sympathise. I've been in that awful dark place from progesterone. Suicidal mood swings, unable to get work done, crippled with anxiety, it was hell.
I was intolerant to progesterone in three different types of patch and pill form including the 3-monthly version, and I was also very resistant to the idea of a Mirena coil (I'm 46 and been in peri for 5 years).
I finally got convinced to have a Mirena coil after I got a referral to a menopause clinic and talked to a nurse practitioner who really knew her stuff. She explained I wouldn't get the mood swings from peri regimes any more with a coil because the progesterone release is lower and constant, so I wouldn't get the peaks and troughs, and also the progesterone would be where it's needed, not in the entire body. Three months on... so far she is right! She also reminded me that if I wasn't happy with it, I can have it removed any time I want. Apart from a little string high up in the vagina, I wouldn't know it was there. There is a tiny bit of blood still, but this is supposed to stop soon and compared to how awful I was feeling before, it's worth it.
Like you, I felt like I was running out of options and the benefits of the oestrogen were too good to risk losing as they'd really improved my quality of life. If you decide to try a coil and if it's possible, go to a menopause clinic/gynae expert/sexual health clinic for the fitting - someone who does it all the time, as opposed to your regular GP surgery, where they might not be as well practised. I was expecting the fitting to be awful, so as a result it was far less painful than I expected. Bearable.
If I think about it too much, I still feel slightly grossed out at the thought of a coil inside me for 4-5 years, but I'm here and no longer getting waves of suicidal thoughts, so it feels worth it.
I have had a few minor anxiety surges since I had the coil fitted, which the nurse thinks are my own peri hormones, so I've now got low-dose antidepressants for those as well.
I'm not trying to sway you one way or the other, just wanted to let you know I understand a bit of what you're going through and the coil might not be as bad as you think, certainly less invasive than hysterectomy. Sorry for rambling on, hope some of it is of use.
