Hello PaulineW.
I know exactly how you feel. On my good days I feel pretty normal but I never know when they will occur, I hate the unpredictability of it all. The last few weeks I have been waking up about 5am with an adrenalin surge and then feeling on edge all day. I am assuming this is another phase but goodness knows how long it will last.
This menopause business is truly horrible and if it wasn't for this site I would find it a very lonely time.
I hope you feel better soon, take care and keep posting.
K.
