It won't! It's The Change. By reading sites on GOOGLE, unless they are UK and medic led, what do you expect to find out, other than giving your brain too much to whizz about

Hot flushes can cause panic attacks. Anxiety causes shortness of breath. So SING! as loud as you are able to in the shower, sing under your breath and concentrate on the singing ...... my music teacher told me that very few people breath correctly so singing can help enormously.
Eating regularly can ease anxiety surges, that is, every 3 hours 24/7 ....... relaxation therapy helped me for a while, my biggest problem being, finding time to relax but oh my cat enjoyed it when I did sit down ........ Yoga, swimming, gentle exercise can help - several years ago I was unable to leave the house even to go into our garden

but with
Valium as necessary, relaxation therapy and time I improved.
I never let our cupboards go bare, so I'm not pushed into a corner to have to shop right this minute. I don't plan too far ahead so that I am not plagued by anxiety.
