Kerrieann - the anxiety could be hormonal. The Dr confirmed to me this morning that anxiety can be hormonal at menopause. In my case, I had panic attacks in my twenties and thirties and resolved them with yoga and meditation practice. However the Dr told me that if you have a history of panic attacks, it makes one more susceptible to them occurring at menopause.
I had had no problems with panic attacks for years (I'm 51) but over the last few months my anxiety sky rocketed. However I put it down to the stress of an impending move to another country (which fell through when all this happened) and I didn't realise that there was an underlying medical reason for the way I felt - I really wish I had known as I just put it down to the stress I was under in organising a move and taking on another college course.
If you can, I would go and see if you can get some medical checks with a Dr. And I keep my fingers crossed that your Dr is a good one.
When I can't sleep, I play a relaxation CD - a guided body scan meditation by Jon Kabat-Zinn - it helps enormously. I also do loving kindness (metta) meditation for every part of my body. I start with my little toe and I silently say "may my little toe be safe and well, may my little toe be peaceful and happy" - and I do this for every single body part I can think of and then go on to muscles, bones, nerves, organs etc - it really helps me mentally.
Traditionally loving kindness meditation was taught by the Buddha as an antidote to fear and I've found it very helpful - it gives my mind something to do/focus on other than ruminate and make me feel worse. I also focus on my breath - I say calm as I breathe in and relax as I breathe out (silently to myself) - basically I think it's about trying to find ways to bring one's attention to body sensations as opposed to allowing the mind to go over and over and get caught up in thoughts.
Sending hugs xx
Also, just to add, my sleep was profoundly affected by hot sweats and when I went on HRT it has improved a bit which has helped - that said, I think the progesterone I was given in Nuvelle Continuous was too high for me as it has, at times, made me hyper alert and I've had difficult falling asleep. But I'm changing medications tomorrow and keeping my fingers crossed.
