Hello Zen,
I am sorry you are having such an awful time. I had cyclical mood swings all through my periods such were very much heightened as peri menopause kicked in. I am now on a mirena coil as utrogestan did not suit me, now thankful has settled down, this has evened things out a bit for me.
Prior to going into hrt I did a course of CBT via my gp surgery and this did help me with many problems.
I am so glad you have good friends to talk with, so vital.
More experienced people that I are here on this forum to offer valuable advice. Please ensure your gp is aware of just how bad you feel.
I just wanted to say hello to you
Hugs to all
