Thankyou Silverlady , you seem to be a fountain of knowledge and I have found your links really interesting, I have not had any of my symptoms prior to perimenopause. I have always considered myself a very assertive ,confident woman .I was self employed running 3 businesses at the same time ,looking back there was a build up to these symptoms until I was a quivering wreck my periods changed I missed 3 months then they returned and they are really heavy . I was like you Delilah worried about my sanity and I know what you mean about being suicidal I didn't feel like I wanted to end my life or anything but questioning life. I do have some mobility issues which has took a lot to come to terms with but I don't feel that this could cause the symptoms my GP calls anxiety. I am 52 years and find my mood changes in an instant, I have spent a fortune and tried lots of alternative medicines, the most effective for these symptoms for me is Magnesium and Quiet Life. This week has been horrendous starting on Sunday that tightness in the top of my stomach ,jittering ,no sleep wanting to leave home (fight or flight)imagination was running wild etc. then today I am as calm as anything love everybody my usual sociable self. It is interesting to note that my period was due yesterday and it hasn't arrived yet. I think it is the worry of when will this end, it is the uncertainty of is it menopause or is it something else and the dread of the next episode. You ladies are fantastic and reassure me that this is normal ,and have certainly done your research. I am so grateful ,
